That viral WhatsApp warning is wrong – but the app does have privacy concerns
Klosowski told Africa Check: 'I think it's important to think through how much data the company collects – everything it can – and what it uses it for – mostly to sell advertising. That broad collection of data consolidated with one company gives them a lot of power, and it's not always clear to people just how much the company collects.'
Meta, with which WhatsApp shares data, mostly uses the information it collects for advertising, linking data from Whatsapp with your activity on other apps and across the web. (Meta will soon introduce ads to WhatsApp itself.)
This means the company could, for example, use the information that you sent a message on WhatsApp from Johannesburg on a phone with a short battery life, along with other device information, to show you an advert for a new phone with a long battery life while you are browsing the web on your laptop.
Tech outlet Futurism has also reported that Facebook has previously taken advantage of what it called 'moments of psychological vulnerability', like stress or body image issues, to target advertising at certain users, including teenagers.
Knowles pointed out some other, more direct privacy concerns: 'If Meta is hacked, your unencrypted data, like your IP address or chat backups, could be exposed.' The same would be true of your personal messages if your cloud storage provider were hacked.
Meta may also hand over data to governments in response to legal requests. And for sensitive communications, even a small amount of information can be extremely revealing.
Klosowski said: 'With WhatsApp and chat messaging apps specifically, the metadata of who you are communicating with and when can reveal a lot about who you are, where you are, and what your needs may be.' While this kind of data may not seem important in the moment, he emphasised that this 'can be worrisome for some in the future if legal or personal situations change'.
The EFF offers examples of how this might work. It could, for instance, be determined that someone 'called a gynecologist, spoke for a half hour, and then called the local abortion clinic's number later that day'.
This is data that is collected from all WhatsApp users, even those who do not engage with Meta AI. But Meta's chatbot comes with additional privacy concerns.

That viral WhatsApp warning is wrong – but the app does have privacy concerns
While WhatsApp does not collect message content, there are situations in which this could be exposed to third parties. For example, Knowles told us that if you chose to back up copies of your chat history to a cloud storage provider, such as Google Drive or iCloud, these might be unencrypted (or unlocked), and the contents accessible to your cloud service provider.

Instagram may know where you live! Turn OFF location sharing
Instagram users are warning about a new location sharing feature, fearing that the hugely popular app could be putting people in danger by revealing their whereabouts without their knowledge. The Meta-owned image sharing platform added an option which shares locations using an Instagram map, similar to a feature rival Snapchat has offered since 2017. Some users have since been shocked to discover that their location was being shared, viral posts have shown. 'Mine was turned on and my home address was showing for all of my followers to see,' Instagram user Lindsey Bell wrote in reply to a warning posted by 'Bachelor' reality television personality Kelley Flanagan to her 300 000 TikTok followers. 'Turned it off immediately once I knew but had me feeling absolutely sick about it.' In a TikTok video, Flanagan called Instagram's new location sharing feature 'dangerous' and gave step-by-step instructions on how to make sure it is turned off. Instagram chief Adam Mosseri fired off a post on Meta-owned Threads stressing that Instagram location sharing is off by default, meaning users need to opt in for it to be active. 'Quick Friend Map clarification, your location will only be shared if you decide to share it, and if you do, it can only be shared with a limited group of people you choose,' Mosseri wrote. 'To start, location sharing is completely off.' The feature was added as a way for friends to better connect with one another, sharing posts from 'cool spots,' Instagram said in a blog post. Users can be selective regarding who they share locations with, and can turn it off whenever they wish, according to Instagram. Wariness regarding whether Instagram is watching out for user privacy comes just a week after a federal jury in San Francisco sided with women who accused Meta of exploiting health data gathered by the Flo app, which tracks menstruation and efforts to get pregnant. A jury concluded that Meta used women's sensitive health data to better target money-making ads, according to law firm Labaton Keller Sucharow, which represented the plaintiffs. Evidence at trial showed Meta was aware it was getting confidential health data from the third-party app, and that some employees appeared to mock the nature of the information, the law firm contended. 'This case was about more than just data – it was about dignity, trust, and accountability,' lead attorney Carol Villegas said in a blog post. Damages in the suit have yet to be determined.

OpenAI releases ChatGPT-5 as AI race accelerates
US - OpenAI released a keenly awaited new generation of its hallmark ChatGPT on Thursday, touting "significant" advancements in artificial intelligence capabilities as a global race over the technology accelerates. ChatGPT-5 is rolling out free to all users of the AI tool, which is used by nearly 700 million people weekly, OpenAI said in a briefing with journalists. Co-founder and chief executive Sam Altman touted this latest iteration as "clearly a model that is generally intelligent." Altman cautioned that there is still work to be done to achieve the kind of artificial general intelligence (AGI) that thinks the way people do. "This is not a model that continuously learns as it is deployed from new things it finds, which is something that, to me, feels like it should be part of an AGI," Altman said. "But the level of capability here is a huge improvement." Industry analysts have heralded the arrival of an AI era in which genius computers transform how humans work and play. "As the pace of AI progress accelerates, developing super-intelligence is coming into sight," Meta chief executive Mark Zuckerberg wrote in a recent memo. "I believe this will be the beginning of a new era for humanity." Altman said there were "orders of magnitude more gains" to come on the path toward AGI. "Obviously... you have to invest in compute (power) at an eye watering rate to get that, but we intend to keep doing it." Tech industry rivals Amazon, Google, Meta, Microsoft and Elon Musk's xAI have been pouring billions of dollars into artificial intelligence since the blockbuster launch of the first version of ChatGPT in late 2022. Chinese startup DeepSeek shook up the AI sector early this year with a model that delivers high performance using less costly chips. - 'PhD-level expert' - With fierce competition around the world over the technology, Altman said ChatGPT-5 led the pack in coding, writing, health care and much more. "GPT-3 felt to me like talking to a high school student - ask a question, maybe you get a right answer, maybe you'll get something crazy," Altman said. "GPT-4 felt like you're talking to a college student; GPT-5 is the first time that it really feels like talking to a PhD-level expert in any topic." Altman expects the ability to create software programs on demand - so-called "vibe-coding" - to be a "defining part of the new ChatGPT-5 era." In a blog post, British AI expert Simon Willison wrote about getting early access to ChatGPT-5. "My verdict: it's just good at stuff," Willison wrote. "It doesn't feel like a dramatic leap ahead from other (large language models) but it exudes competence - it rarely messes up, and frequently impresses me." However Musk wrote on X, formerly Twitter, that his Grok 4 Heavy AI model "was smarter" than ChatGPT-5. - Honest AI? - ChatGPT-5 was trained to be trustworthy and stick to providing answers as helpful as possible without aiding seemingly harmful missions, according to OpenAI safety research lead Alex Beutel. "We built evaluations to measure the prevalence of deception and trained the model to be honest," Beutel said. ChatGPT-5 is trained to generate "safe completions," sticking to high-level information that can't be used to cause harm, according to Beutel. The company this week also released two new AI models that can be downloaded for free and altered by users, to challenge similar offerings by rivals. The release of "open-weight language models" comes as OpenAI is under pressure to share inner workings of its software in the spirit of its origin as a nonprofit.
