Microsoft/GitHub is doing something clever this time. They know where the developers are and know that the new consumers are developers, hence 'devsumers'.

So how does Microsoft make them happy? Give 'em free stuff: Free repositories, student pack, ebooks, courses, cloud credits, etc and they come running back to GitHub. There's Sign in with GitHub which makes it easy to claim all the freebies, unlike the rest of the alternatives.

This is why the majority of developers will stay and some would realise that it will all go down and will leave Github and self-host their own git server instead.
