I started the campaign to move us from Bitbucket to Github before the Microsoft acquisition. If I knew MS would be involved, I'd have campaigned for something else. I would never recommend any Microsoft product.

It took ages for us to get permission and licenses. We only recently finished moving the last repos over and shut down Bitbucket.

If AWS offered a product like GH, I could probably unilaterally start moving to that. Any other alternative would take 3-4 years of meetings, budgets, lawyers, and other such nonsense before we could declare we'd left Github.
