It's sad to see GitHub moving slowly into spreading itself too thin, instead of just improving the platform they have. They now try to replace CI services, donation platforms and now remote code editors.
Seems their core service is still holding up so far, but with all these moves in different directions, I'm getting a bit worried that the SCM and software collaboration part will be left out. I think GitHub becoming SourceForgeV2 is closer than people think. It's bound to happen at one point.
