Microsoft employ over 100,000 engineers. I'd advise against assuming that everything produced by any of them is bad because of bugs in Windows.
They seem to be alienating a lot of their users right now in a lot of different products. There's a significant surge in open source software right now and Linux and all the people that are coming over are a bit more than usual. Their customer base seems tired of the game.
Not op, and I generally agree with your assumption but not for Microsoft, as I don't think it's limited to Windows:
Teams, Office (especially online), One Drive, SharePoint, Azure, GitHub, LinkedIn, all became very shitty and partially unusable with increasing number of weird bugs or problems lately.
This is not about individual employees. It’s in the nature of being an employee to be beholden to what’s incentivized by their company’s management and structure.
The problems with Windows today have nothing to do with bugs but with the strategic vision of Nadella.
This is also still small/unimportant enough not to be poisoned by their broken corporate culture.
The criticism was directed at the company's product, not the employees...
