It’s not that they think they know better, it’s that they know power users are the minority.
Everything is about minimizing expense to an extreme degree to drive “growth” in the current tech economy, so there’s little focus put into things that do not test as an immediate boost to marketability.
I wish this was the reason. It's just mediocrity and pure, raw ignorance. A result of throwing bodies into the technology industry in a desperate attempt to get the software out.
Considering how much money are poured into AI development would not say that "everything is about minimizing expense". But it is true that user interfaces are not something that will sell your application to the masses.
But to be honest, trying to sell any kind of "advanced software tools" (like compilers or other very specialized tools that provide small gains compared to existing free ones) for "power users" is extremely hard. Was involved in something similar in ~2010 and many power user think they don't need it or they can do it better themselves but anyhow does not want to pay for a complex tool.
Probably the web interfaces is exactly a manifestation of that, many users trying to implement things themselves because they know better. But I prefer writing interfaces with React than with Win32 so I think there is progress.
Which advanced UX do you implement? MacOS? Windows? Gnome or KDE behaviour? CDE?
One could sniff the user-agent and adapt to a recognized OS behaviour but we all see how superficially shallow the UX on the web is. I've given up on expecting anything advanced.
Any UI is as good as its base layer. We wouldn’t have $subj if MS didn’t implement it. But then when you tell them that the browser UI model is just useless crap with smooth animations, you get hellvoted, yelled and thrown fragile css/$()/useX incantantions at.

Browser advanced UX. Not current browser UX, but a hypothetical one which doesn’t suck.
