Earlier quoted context omitted.
Developers didn't get a choice. It was either "pay for Apple's development services" or "don't publish apps" which isn't a very competitive or fair option when the App Store can arbitrarily reject you.
Of course they did: they could have just chosen to not publish apps which would have crippled iOS. The only reason it feels existential is because developers made a Faustian bargain from the beginnning.
Today, Apple removes apps like ICEBlock and Navalny's voting guide; they're directly complicit in using the App Store to steer political agendas. This is what developers were unhappy with, and we're seeing this type of censorship specifically because iOS has no App Store alternative. On macOS, for example, there is no way for Apple to be strongarmed into censorship because users can install any valid binary they choose.
On iOS, developers and users do not have that same choice. There is no natural competition.
