We do use other providers, but as stated Docker Hub is the defacto standard so it would be counterproductive for us to abandon it entirely.

We don't "want free stuff", we pay for docker hub for several accounts, but they offer and promote an Open Source program that we have been part of, that simply does not function properly, and that is our complaint.

Your attitude of "well it's free so it's fine if it's shit, just go somewhere else" is wildly unhelpful to everyone.
