I am not the GP. To me, supporting GitHub is like supporting Jetbrains. I know they're good people. I know they're trying to do good things. However, I will always have a nagging feeling that wishes that the universe was somehow different and that their business model made it possible for them to freely and openly offer all their software.
I guess I can include things like Aerospike and even Gitlab in that group. I don't actively wish for them to succeed either. I am glad they exist and I actively use their products but I would not cheer for any of them.
