Cut and dry if the open-source contributors are "blocked persons", but are they?

They'd no longer be allowed to contribute to the project, but does someone having contributed in the past mean the sanction on the project extends to their person? Github themselves provided hosting to the project.

It's quite possible these contributors had forks, which is why they were blocked.

More importantly, these contributors are likely to have local forks when they can quickly upload under a different name. They can still create new accounts though.

And GitHub can continue to ban them under OFAC compliance?

Yes it almost certainly does.

Sanctions work because they are virulent.
