Note that my issue with EXX being brought up is that it is superficial, to the point of being deceptive to the kind of threats Microsoft+Github are most likely to pose if Nadella et al do have their own malicious plans. But I think Microsoft's support for a healthy OSS ecosystem, via Github and things like VS Code, is genuine. Not necessarily out of altruism, but because it's one of the few ways they can have an edge into the future and not fall into stagnation like IBM.
