Im trying to understand how UMU uses prefixes

plain Wine prefixes work just like a Windows drive, I just execute WineCFG or regedit or install more software in the same prefix if I need to

but UMU seems even more focused to the one program per prefix approach

I know it uses a read only runtime, but how does it use prefixes? Bottles doesn’t treat them like they do with Wine ones (allowing you to add shortcuts for different programs in the prefix for example, but Bottles offers you to use Game Files outside of the prefix too)

what I meant was, Chromium’s influence and control on the whole web

the real problem isn’t Chrome, it’s Chromium
