I'm fairly sure a good chunk of Github isn't open sourced either, no?
You appear to be correct. I had never even thought to check and just assumed that it was!
You can sense the irony there.
This is why I use GitLab
I second this, considering the fact that the two platforms have an equivalent feature set, there's also Drew Devault's platform: source hut (I think) which seems very good.
No, it’s closed source.
Can't understand why, since is only the frontend :(
