well, I mean, of course... Facebook is still the proverbial 500lb gorilla, bad actor or no. Apple's going to be very slow in nuking a big player that drives a huge chunk of device usage.

Eh, I think Facebook would lose more money each day that conflict dragged on until they complied with apple’s policies.

Users can always access Facebook through safari.

Kicking Facebook's apps off the appstore would include WhatsApp, Messenger, and Instagram. It would be a bigger deal than logging into Facebook.com on safari.

Instant antitrust lawsuit if apple did that imo. They already have the good guy points here, no need to go overboard and become the bully.

let's do it... I'd love to eat popcorn and watch that play out.

Even ignoring directly related apps like Messenger, Facebook is the main way I log into a large chunk of unrelated apps on my iPhone including games, food delivery, shopping, etc. Nuking the main Facebook app could cause harm to a huge number of users and third party developers.

You can do into with Facebook over Safari and not the Facebook app.

is it clear whether Facebook would have more to lose than Apple if its app were banned from iOS?

I think Facebook has more to lose. Apple has some of the most loyal customers on the planet, and everyone subconsciously hates Facebook anyway.
