Microsoft didn't buy Github out of the goodness of their heart. They also didn't buy it because of it's significant revenue, a couple hundred million is probably a marketing budget to Microsoft, not something that drives the bottom line. Microsoft also didn't buy it to score appearance points with the socially conscious dev community that populated most of Github, although it was a nice PR story for a bit. You could say the ICE thing has driven all that goodwill away.
Microsoft bought Github for the data set. To mine code to train models to write code to put developers out of business. Microsoft is coming for all of your jobs. They aren't investing billions in AI research and Open AI for philanthropy. The sooner people realize this the better.
Sure it's tin-foil, but it's a hill I am willing to die on.
