The occasional prominent developer has left GitHub for GitLab, but it hasn’t made much of a difference. I don’t see organizations moving off GitHub if they’re already using it. I think GitHub is independent enough from Microsoft that the two could take different stances on these disputes. Certainly I’d expect a DMCA takedown of content on a Microsoft service like OneDrive to be ultimately handled differently from a takedown aimed at source code on GitHub...
Thankfully I am not yet required to sign on to github using 2FA that can only be confirmed on a Zune. Microsoft has been pretty good at leveraging github for the publicity of supporting developers (hosting informational streams and the like) while leaving the platform pretty independent.
I wouldn't be surprised if Microsoft viewed Github like McDonalds views the Ronald McDonald House - a long term PR investment that's well worth the marginal cost.
Except that Facebook has been integrating their sign on service into various acquisitions - using Zune (or any hardware) was quite hyperbolic of me. For a more even handed comparison: I'm not required to use a Live login to authorize with github.
I'm a bit doubtful of this. It's possible but Microsoft uses Live for both business and gaming, but they've only had a track record of forcing Live account adoption onto users in the gaming sphere. It may happen, sure, but I don't think it's likely.
That all said I didn't think it was likely that Minecraft would switch over to using Live accounts since Minecraft is so famously cross platform and Live accounts have struggled with that in the past.
They're also boiling the frog on Windows local accounts at the moment. It's no longer possible to set up a new install of Home, or Windows 10 (any SKU) in S mode with a local account without either disconnecting internet during installation or going back and converting to a local account after
