I don't think having conditions to certain things qualify as "I'm fine with it"

"I'm fine with people eating meat, as long as they declare so when we go out" like why? Why does it matter?

Both GP's and your example in effect mean "I'm fine with other people doing this, but I don't want to have anything to do with it, or at least be able to decide case-by-case."

Which is a valid stance IMO.

In the OP, a vibecoded UI when the whole project emphasizes "I did this myself, from scratch" is a bit awkward.

Does "I did this myself" mean they read all the relevant specs and then wrote the code - or did they just write the prompts themselves?

Edit: OP already answered and confirmed that they in fact did write the code themselves.
