No, but nobody ever in anybodies wildest dreams would hold Apple liable for having one application in the store (among thousands) that belongs to one service (among dozens) that a couple of users (among millions) once discussed organizing violence (which they never organized, and the violence that happened has no relation to anything there). Pretending like Apple (or Google, or Twitter, or Facebook) censor politically because they want to "avoid liability" is either ignorance or hope that your opponent is so ignorant that they do not know what liability is and how it works.

Apple is perfectly within their rights as a private company to ban applications from their platform solely based on it's user base being a huge gaggle of toxic assholes.

I don't think you will find any sympathy for neo-fascists here.

Parler is taking Apple to court over this, which will be hilarious to watch.

Apple was targeted by left wing activists for just hosting the NRA App.

Liability comes in many forms.

"Targeted" and "liability" are two different things. You can be targeted by left wing activists for literally anything. There are people who think yoga and veganism and SpongeBob SquarePants are racist. But Apple knows very well there's no "liability" in that and he doesn't have to jump each time a loudmouth on the internet gets vapors. When they do something, it's because they want to do it, not because some kind of "liability".
