@melroy I don't think you can really be upset about anyone putting through bad code. According to the philosophy as I understand it, bad code (intentionally so or otherwise) is a useful contribution and you are basically soliciting it. You supposedly have some way other than code review to ensure nothing harmful gets through and it has to do with the reputation of the contributor. Since you already knew @ernest and clearly have a bad opinion of him, how did it happen?
I did not and could not review the PRs themselves. So I am just going on the information as presented here. Sounds like @ernest put through some code (either into kbin or mbin not clear on that) which he knew was not 100% highest quality but which error was not critical or devastating. And that it could easily be found and fixed. Partially he did this to learn more about this governance model. A model which has apparently been developed in direct opposition to his own. Is it approximately accurate?
If so, sounds a bit mischievous at the worst.
I really can't recommend Tyranny of Structurelessness highly enough.
