Twitter owner Elon Musk on Monday opened fire against Apple over its tight control of what is allowed on the App Store, saying the iPhone maker has threatened to oust his recently acquired social media platform.

Musk also joined the chorus crying foul over a 30 percent fee Apple collects on transactions via its App Store — the sole gateway for applications to get onto its billion plus mobile devices.

A series of tweets fired off by Musk included a meme of a car with his first name on it veering onto a highway off-ramp labeled “Go to War,” instead of continuing onwards towards “Pay 30%.”

Apple did not immediately reply to an AFP request for comment.

Both Apple and Google require social networking services on their app stores to have effective systems for moderating harmful or abusive content.
