GitHub doesn't do anything but centralise a bunch of services other companies (including Microsoft) have SaaS for. There's literally hundreds of git hosting platforms, kaban boards, issue trackers, CI services, code search tools out there.. All GitHub does is bring it together. It does not really have any kind of lock-in.

It does have lock-in because almost everyone is on GitHub and if they move they lose access to that community.

e.: people mentioning "Github profiles" when discussing preparing for interviews.
