Problem 1 is also largely solved by ditching GitHub in favor of an environment where you control who is allowed to submit a PR. GitHub is convenient but if you have problems with vibe code volume, choosing to host with a company who heavily incentivizes it and has a commercial interest in doing so is self-defeating. Treat it the same as any other free service that enshittified after several years of market capture on the basis of being free and convenient.
Problem 2 is the actual reason the project tanked and your take is spot on.
