But really, if your project is mature enough and you have the bandwidth, just host it yourself. Gogs, Gitlab, cgit .. lots of FOSS implementations to choose from.
We saw another story like this come across the front page this week. The author is less well known (also happens to reside in Russia), and claimed that he had trouble even getting an e-mail response from the given support pathways for appeal. Sounds like it eventually got sorted out, but not without much waiting and effort from the maintainer.
So when GitHub CEO Mr. Friedman jumps in and pats himself on the back for getting this account restored in less than an hour, I can only roll my eyes. To try to sell it like this is an 'average' response to these type of appeals is a little disingenuous.
If I were starting a company today, I would absolutely self-host my repository to guarantee my business is never harmed by some automated flag that could total lock me out of my own work. We use GitLab Community Edition at my company. It is fantastic, and we are in full control.
You should check out RhodeCode too for self-hosting your own code, with extra security features to make sure it's well protected
