Twitter's new owner decided to pick a fight with Apple, posting a slew of tweets criticizing the tech company and a meme claiming he would "go to war" with the iPhone maker.
Elon Musk has said Apple has halted most of its advertising on Twitter and accused the company of threatening to remove the platform from its app store.
The feud comes as many companies have halted spending on Twitter amid concerns about Mr Musk's content moderation plans for the site.
Apple did not immediately respond to a request for comment on Musk’s tweets. The company has previously shown it’s willing to remove apps from its app store over concerns about their ability to moderate harmful content or if they attempt to circumvent the cut Apple takes from in-app purchases and subscriptions.
