I'm not a fan of github for other reasons, but how the heck would your solution work for searchability and discoverability, two of github's largest values?

Post the onion link on the clearweb, and then those intermediary sites are mere pawns.

This could work for distribution but it's not a solution for shielding the developer(s). If you have already publicly published code with attribution I would not consider tor + forward pawns to be 100% invulnerable to forensics to determine authorship. So now you're looking at tackling code transformation without obfuscation to cover provenance, which sounds non-trivial.

(Your comment made me wonder if coPilot can also be used to fingerprint developers based on their existing code.)

If the sites/authors are out of US jurisdiction, then there's not a whole lot that could be done, so there's that.
