alt Hacker NewsA lot of developers (and thereby most on HN, I guess) see Microsoft only from the perspective of a private consumer. From the perspective of a normal non-technical company though, Microsoft is this giant that has spread its products throughout your organisation like a cancer and you can never free yourself from it. For Microsoft's main business it's irrelevant if VSCode is mostly open source or not. That is why these gestures never meant anything in the first place.
It doesn't matter if some Microsoft trinkets are open sourced while AD is not and while you still can't connect your open source DNS and DHCP server to a Microsoft domain controller. Or have your open source email client be 100% compatible with the proprietary Exchange protocol.
There's also business value in "good enough" that Microsoft satisfies for enterprises. You get a lot of stuff "for free" with something like an E5 license: EDR, DLP, MDM, a full cloud IAM system, and a ton of cross app magic for the lowest common denominator of non-technical employees that you just aren't going to get without spending considerable developer effort to piece together a stack yourself.
What looks like cancer to us looks like a massive reduction in operational risk to a CFO/CIO.
This is especially true if your core business has nothing to do with software or tech. Much easier to cut a check to Redmond. Microsoft is basically a utility company for enterprise now, it's commoditized IT. "Do what you do best, outsource the rest."
