Linking this comment here https://news.ycombinator.com/item?id=30019307 that designers at Microsoft use Mac and have been given more power than they should.
This has been the case for a while. I worked on the Windows Desktop Experience Team from Win7-Win10. Starting around Win8, the designers had full control, and most crucially essentially none of the designers use Windows.
I spent far too many years of my career sitting in conference rooms explaining to the newest designer (because they seem to rotate every 6-18 months) with a shiny Macbook why various ideas had been tried and failed in usability studies because our users want X, Y, and Z.
