My issue isn’t with any single particular instance of censorship, but with Apple’s
willingness to censor, regardless of market or local regulations.
This is exemplified by this above-and-beyond blocking, as well as their censorship of entirely legal content (e.g. nudity) in the US app store.
I would have much less issue with them if there were a setting to install an alternative app store on the iPhone; then it would simply be editorializing. As it stands there is no way for me to persist e.g. a gay porn app on my iPhone, and that crosses the line into voluntary censorship of legal content by Apple.
