Apple and Elon Musk’s Twitter are on a collision course

$Tesla(TSLA.US)$ Musk wants to vastly increase the amount of money the company makes through subscriptions while opening up the site to more “free speech.”
This creates a risk that $Twitter (Delisted)(TWTR.US)$ could violate $Apple(AAPL.US)$ or $Alphabet-A(GOOGL.US)$ ’s app rules in a way that slows down the company or even gets its software booted from app stores.
Battle lines are being drawn. Last week, Musk complained about app store fees, which are between 15% and 30% of digital sales, in a tweet.
