I’m utterly baffled what the author is talking about with regards to “toxic” output. While I agree Claude’s prose is a mess right now, he never explains what he’s talking about when he calls it toxic.

I don't know about the author but for me it's actually starting to induce enough stress that it's starting to negatively affect me. I think that qualifies as toxic. I actively feel like I need this gone from my life at this point. It's quite a bit of work to try and engineer it out, so at this point I'd rather put the effort into trying to switch everything to Codex just to get away from it.
