> MS 2020 is far away from MS 2010.

I haven't seen evidence of this. Their OS is at least as user hostile as before and they desperately seek developers.

If I have a specific technical problem I have to slay hundreds of sales people before I find someone with real expertise.

That they aren't as dominant as before is probably due to the fact that they have few developers and need to regain some. Financially Office is probably the largest income and sure, the standard corporate AD solutions are wide spread. But their cloud tech seems to be restricted to very large companies and I haven't seen much of it.
