It is the second time in just a few weeks that the Twitter and Tesla billionaire has taken a jab at his tech rival Zuckerberg.
Elon Musk has slammed WhatsApp on Twitter amid reports that the app owned by Mark Zuckerberg is listening to users.
Musk in a Twitter post on Wednesday said the messaging app 'cannot be trusted' in response to a tweet thread from one user who said WhatsApp accessed their phone's mics while they slept.
It is the second time in just a few weeks that the Twitter and Tesla billionaire has taken a jab at his tech rival Zuckerberg, accusing him of 'bias' for supporting Democrats through his campaign donations, Daily Mail reports.
Musk's comment came in response to a screenshot shared by Foad Dabiri, who showed how his WhatsApp mic was switched on nine times between 4:20 am to 6:53 am while he was asleep.
WhatsApp responded to the issue on its Twitter account, noting that Dabiri's incident 'is a bug on Android.' But the issue has persisted for months.
The incident is not limited to Dabiri, as many WhatsApp users have reported seeing the microphone activated in the background over the past month or more.
Some users have suggested restarting the device will fix the issue or 'tap the mic access notification shortcut to toggle it off and then turn it back on,' a Redditor shared.
“Over the last 24 hours we’ve been in touch with a Twitter engineer who posted an issue with his Pixel phone and WhatsApp,' WhatsApp tweeted.
“We believe this is a bug on Android that misattributes information in their Privacy Dashboard and have asked Google to investigate and remediate.
“Users have full control over their mic settings once granted permission, WhatsApp only accesses the mic when a user is making a call or recording a voice note or video - and even then, these communications are protected by end-to-end encryption so WhatsApp cannot hear them.”
Privacy Dashboard is a Google-owned service that lets users see which apps are accessing their data, which have permission and when it is happening.
WhatsApp's tweet about Dabiri's post suggests Google's Privacy Dashboard is to blame for the issue.
One Twitter user responded to WhatsApp's tweet: 'If that's 100% true, you should sue @elonmusk for defamation of the brand, would you do that?'
WhatsApp is the most popular messaging app, with around two billion active users worldwide.
Facebook purchased WhatsApp in 2014 with a bid of $16 billion.
Musk and Meta CEO Mark Zuckerberg have been vocal about their distaste for each other.
In 2022, the Twitter CEO accused Zuckerberg of exercising too much control over public debates, describing him as 'Zuckerberg the 14th' in a mocking reference to the Sun King.
And this year, Zuckerberg's Meta announced it was taking on Twitter with a new similar app set to be released soon.
