I thought HN frowned on metacomments, and here it goes, talking about GitLab again, in a Github topic...
But the facts are such:
1) GitLab is a YCombinator incubated company.
2) GitLab and GitHub are direct competitors
3) It's almost always relevant to the discussion, in this case; "How could it be done differently, how /has/ it been done differently"
In this case I think it's fair to bring up the direct comparison of github and gitlab. The only thing I would say could improve the situation was having github representation on here too.
If this is how all marketing would always look like, I wouldn't hate it like I now do.
