Point 1, their problem, not mine. If they don't want to change from their philosophy based "free" paradigm then they never have to, but they'll never "win" the desktop. The only way this happens is with ad and marketing dollars, full stop. How they get to that point is their issue to solve.
Point 2, It is a serious issue, whether or not it is for you is another matter. but I know better than to even try to get my girlfriend to use win32 outlook, when the much simpler UWP mail client is available. She knew how to use that in seconds, traditional outlook, she would need a manual and all the controls for things she will never do were just in the way. I don't understand why power users cannot grasp that they are a TINY portion of the market, an that the money, and mindshare, is making stuff that's more grandma friendly and simplified with just core features. So yes, it's a serious issues if you are trying to get people to switch, if you aren't, as distro makers have made abundantly clear for 15+ years, then I guess it's a non issue.
We just ditched an old web front end for time clock management, from a 2005 era one to something from current year. The techs tell me there are almost no time clock related calls now. There used to be all sorts of buttons for things like audit time, check this, check that other thing, etc. They removed all that and just left IN, OUT, LUNCH. The auditors and all have a separate page for all the complication. Calls dropped 90% for issues with that system.
