I suspect GitHub - and, to some extent, Microsoft at large - is going through something of a trust thermocline[1] event right now. There's been frustration brewing with GitHub as an open source platform for a while, but not enough for any one project to leave by itself; but over time enough has built up that various projects decided they had the last straw, and it's getting to be a bit viral via the HN front page.
I think it remains to be seen how large this moment actually is, but it's something I've been thinking about re: GitHub for a while now. Also, I suspect the unrest around Windows' AI/adware enshittification and the forced deprecation of Windows 10 are casting a shadow on everything Microsoft-ish at the moment, too.
[1] The original Twitter thread that brought this up as a concept is https://threadreaderapp.com/thread/1588115310124539904.html. This is in the context of digital media outlets, but I think it's easy to see how it can apply more broadly. There are some other articles out there for the searching if you're interested.
