Apple has also threatened to withhold Twitter from its App Store, but won’t tell us why
— Elon Musk (@elonmusk) November 28, 2022
The problem here for Apple is that Musk would have a very straight forward lawsuit which would not have anything to do with liberal popular opinion or liberal rhetoric. Apple (unlike advertisers) would have to actually have a reason to remove an application (that currently exists) from their phone. Just not wanting it (or banning it for political reasons is not a good enough reason). Many legal analysts have suggested that Musk would have good standing and Apple would have very little in response.
If the Twitter app became so unpopular that nobody was downloading it or using it then Apple would have real business reasons. If there was literally dangerous activity on Twitter that did not previously exist (dangerous as in something illegal - not something un-woke) then they would have just cause. But simply because they do not like Elon Musk or how he is running Twitter?
Moreover, Elon could possibly just decide to start an alternate phone company (or perhaps buy up and existing one) and compete head to head with Apple. I could tell you that there are plenty of conservatives I know who still have Apple products who would make a different decision when they upgrade their next phone or computer (which happens now way more often).
