The thing is even Microsoft in the post Win 10 era is reliant on insiders to test Windows releases nowadays so there's not really much competition for desktop market nor is there anything huge at stake.
At this point I as a regular non-enterprise customer can't even pay for a churn free, ads free, forced apps free security updates only OS like Windows 7 - unexpectedly fast descent into sadness.
(Where possible I run Linux and thankfully it has worked fine so far but some work things still require Windows or Mac.)
