I mean, I’ll take a stab at speaking for Apple fans, and in fact developers. (I’m an ex-employee.)
There are a lot of things we like about the user experience on their platforms, and we appreciate their general interest in privacy while not engaging in the dirty data mining / advertising business of Google and Microsoft. There is a polish on their platforms that is best in class.
But I don’t believe any of us actually support the App Store lockdown situation. It’s probably the biggest black mark on their record. I think they got it right on macOS, requiring the binaries to be notarised (signed digitally) in such a way that malware can be blacklisted. This is a useful security feature. But developers are free to distribute however they want and third party stores like SetApp and Steam coexist happily with the App Store.
100% of their arguments about keeping the App Store as the sole distribution chain are bullshit because macOS is the proof. It’s pure rent-seeking behaviour.
