I grew up through some of the more interesting business practices Microsoft employed, and it's several attempts to harm the Linux ecosystem. I would love to see this move by Microsoft in a positive light, but can't help but be suspicious ? For now the possibilities it opens are great, however I wish I understood Microsoft's strategic view of this and how it might evolve over time for Linux.
This attitude seems pretty dated. This microsoft are no longer the ridiculously dominant force they once were. Linux is a core part of their cloud business now. They have a new CEO, and a lot of time has passed. They are actively trying to change a lot of their culture and approach to things.
I would love to see MS get their crap together, but it still seems like they can't break their addiction to abusive behavior.
