First of all, let’s remember that Github is a fully proprietary service. Using it to host the development of a free software makes no sense if you value freedom.

This is dumb. Where do you draw the line? Is your motherboard firmware open source? Your CPU design? Do you have the CAD models for the office chair you’re sitting on?

It’s not like there aren’t plenty of open source alternatives we could switch to easily in a heartbeat so it’s not like it’s a hard dependency, in the same way that e.g. a language with only a proprietary compiler would be.

I stopped reading after this obviously stupid point.
