Basically everyone is getting shafted.
iPhone is nice, but it has its quirks and stupidities. Android is nice, but has some other stuff I don't like.
I wish there would be a third option that would take the best of those two worlds.
I’m almost in the market for a new phone and I wish there were more options than Android/iPhone. I’m looking at maybe going for a GrapheneOS phone of some sort though
Including app stores installed out of the box on GMS certified devices like the Samsung Galaxy Store (alongside the Play Store).
It just means they will be easier to install via the Play Store without sideloading (making other commercial stores more attractive but not really my cup of tea), and some minor API changes (although auto updating was added even before the ruling so not sure what else there might be).
Personally I'm not concerned about the changes to sideloading since it's a one time mild inconvenience. So I struggle to understand how going to iOS in protest (which doesn't allow persistent sideloading at all without workarounds) makes any sense whatsoever.
Google's original plan would have been really bad, but the new approach is a complete non-issue for me.
