Probably worth mentioning that force is a ref-related activity not a snapshot related activity. Garbage collection might remove unreferenced commits.
This should be done through history rewrites but as other commenters mention - GitHub has its own rights (and GitHub != git).
I’d recommend looking at simpler alternatives. IMO Jujutsu is mature enough for daily usages, and Fossil is a neat alternative if one wants to drop GitHub completely (albeit not very easy to use).
