Well maybe, but with Windows maybe they shouldn't think about power users but power buyers. And power buyers (i.e. medium to large enterprises) care about security, maintainability, backward compatibility, and supportability and yeah lots of stuff has moved to the cloud but the end user has got to use something to get there.
So, the question is, is this creative destruction or just destruction. Not every change is an innovation even in IT and large vendors have a long history of failing in computing usually because they either got sclerotic or too focused on the organization and promoting the organization and too little focused on the customer.
I think that is the crux of the problem actually. Same with Teams, what the buyer wants is misaligned with what the end user wants unfortunately. Most resources are put towards making it an easier sell rather than towards a product the end user loves.
