GitHub was sold because it didn't make too much money. Microsoft bought it for OpenAI only, to train Copilot on the vast amount of code.

Of course, MS every once in a while says that it makes a lot of money, but they don't really say how much is costs to keep it up. Their free tiers are still very generous, even they are buggy as hell - I can't imagine that the profit it makes even dents MS' bottom line (assuming it's not in the red). But at the end of the day the model training is done.

I guess Github doesn't have a lot of use anymore, beside having a lot of users that you can use to experiment with such shenanigans to see what can you get away with.
