One of the things that really worries me is that this seems to be creeping in to desktop OS's as well. It's still possible, for now, to install software on Windows 11 without going through the "Microsoft Store", but I remember having to tweak some security settings to make that possible... and was really alarmed the first time I tried to install software on a fresh install and got blocked and directed to the Microsoft Store.
I've always had mixed feelings about RMS and FSF, mostly due to their hardline attitudes (I'm not opposed to proprietary closed-source software even if I have a preference for FOSS... I think there's room for both) but this trend of software installation gate-keeping that came from mobile has me really worried (and I've never been much of a mobile user either, so any creep from mobile into desktop is always unwelcome and alarming to me).
