Opus 5 tells me no all the time (code cli and web). It's reasons are usually pretty well argued though.

Opus 4.7 would flat out refuse to follow instructions to the point where it was just too frustrating to use.

I've had refusals for GPT 5.5 before as well (not because of a ToS violation, it just refused to take conversations in directions it felt were in bad taste)
