Apple censoring apps in its own proprietary app-store isn't really a big deal to society as a whole. Apple censoring what other devices are allowed to exist outside their production-lines and what competing products customers are allowed to choose is.
I know that this is a hopeless request but can we stop using the word "censor" when we are really talking about curation, or editorial policy, or private business decisions, etc? Government imposed restrictions on speech and/or commerce is something entirely different from plain old business decisions and it would be nice if we didn't conflate the two things by overloading the meaning of "censorship".
If you control software distribution on a plaform, you directly or indirectly control every information that customers of that platform receive. I think this covers censorship.
Of course iOS does not have a dominant position in the market yet, so censorship is limited by the customers choice to switch to another device. But as I explained above, the moment to speak against the control is now, as long as there are still alternatives left.
I think this "plain old business decision" is a political issue of great importance.
