It’s the same as with Linux, GIMP, LibreOffice or OnlyOffice. Some people are so used to their routines that they expect everything to work the same and get easily pissed when not.
I’m not missing anything, OP complained about people not easily ditching closed/centralized software and I gave an answer.
I know devs are doing it as a hobby or with donations, that’s on them and they know who their target will be and how much effort is it worth to do it user-friendly or not or how big of a scope they aim for.
We’re talking about the normal user and why they decide to stick to centralized or move to FOSS and why it’s so hard for them to do it.
