As somebody who has worked a bit with a few microsoft bound teams : it has to do with the teams and their managers.
Some teams were a treat to work with and are completely open to my comments or questions, and ready to serve the user’s needs.
Other teams are terrible. They dont respond, they do whatever the fuck they want or what their managers tell them and pump out garbage that makes no sense to the users.
Dotnet clr, refit, fluint ui blazor, …
All nice teams.
Fluentui ( webcomponents ), wpf, parts of windows teams, …
Not so much
And for that reply, you get a useless upvote :')
