Elon Musk has claimed 'WhatsApp cannot be trusted' in a bizarre Tweet.
The Twitter chief was responding to one user who claimed WhatsApp had been using the microphone in the background of his phone.
The user wrote: "WhatsApp has been using the microphone in the background, while I was asleep and since I woke up at 6AM (and that's just a part of the timeline!) What's going on?"
Mr Musk quote tweeted replying: "WhatsApp cannot be trusted" before replying to another user who said "it's incredible how many people don't realize that WhatsApp is owned by Meta / Facebook."
However, WhatsApp claim the issue reported was a bug on an Android phone.
They replied: "Over the last 24 hours we’ve been in touch with a Twitter engineer who posted an issue with his Pixel phone and WhatsApp. We believe this is a bug on Android that mis-attributes information in their Privacy Dashboard and have asked Google to investigate and remediate."
The billionaire claimed recent changes at the messaging company had disturbed workers greatly.
Mr Musk then bizarrely tweeted to his followers "Trust nothing, not even nothing."
The 51-year-old has previously urged social media users to delete Facebook, a rival messaging app, amid fears over privacy.
The SpaceX and Tesla boss wanted people to sign up to the privacy-focussed messaging app Signal in January after Facebook forced users to agree to controversial terms and conditions by February 8.
The conditions saw private data collected by WhatsApp, including a user’s IP address and phone number, shared with Facebook.
WhatsApp privacy claimed chats with friends or family members would not be affected.
However, following Mr Musk's tweet, there was a reported increase in the number of users using Signal, an encrypted messaging app.
The company tweeted in January: "Verification codes are currently delayed across several providers because so many new people are trying to join Signal right now (we can barely register our excitement). We are working with carriers to resolve this as quickly as possible. Hang in there."
It is not the first time Mr Musk has criticised Facebook after he called the company "lame" last year.
He has previously posted the hashtag #DeleteFacebook during a popular Twitter campaign which was highlighting concerns over privacy.
His companies, SpaceX and Tesla, do not have official Facebook pages after the billionaire demanded they were scrapped in 2018.
He claimed he “didn’t realise" his companies had Facebook pages at the time - after he was criticised by Twitter users for being on the platform.
“I don’t use FB and never have,” Mr Musk tweeted at the time. “So don’t think I’m some kind of martyr or my companies are taking a huge blow.”
"It’s not a political statement and I didn’t do this because someone dared me to do it. Just don’t like Facebook."
