If it is possible, it doesn't mean it will remain possible. Github is still centralized and can change its rules in a blinking of an eye like coming up with some excuse and banning Tor.
In theory, you can also circumvent that using Tor. Simply employ Tor as a proxy and exit through a VPN. Github would then only see the IP address of the VPN, which presumably isn't blacklisted. However, I understand your perspective. Personally, I believe it might be wiser to migrate to your GitLab page, similar to what Samourai did:
