The thing for me is, so much of Microsoft has shown serious improvements over the past decade. You've got Azure's push in the cloud championing (at least some) truly open source community-driven projects like Kubernetes (rather than Amazon's ECS), you've got Office unveiling their new Fluid document format as open source day 1, you've got WSL2, Xbox under Phil Spencer making a huge push to find more equitable ways to satisfy both gamers' desire for more games and developers' need for revenue with Game Pass, the push to bridge console generations with Smart Delivery, the push to bridge console and PC with unified digital licensing...
And then they do things like this. The Windows core team feels to me like a clandestine shadow organization in Microsoft whose location is unknown even to Nadella. Of course, that's not what's happening, and its startling to me that no one has cracked down on them for this shitty behavior.
Its not representative of how Microsoft, by and large, operates today. It is representative of how they used to operate.
