It’s just because I’m a newbie – having been using Linux for one year, and started with Ubuntu simply because that was shipped ready with my laptop. I haven’t found the time to try any other distro yet, because of work & lack of time.
Indeed I remember I was thinking about moving to Linux years ago, exactly when the Amazon-Ubuntu craziness happened, so I thought “some other time”.
Regarding snap & flatpak: I simply don’t like the redundancy philosophy behind them.
