A substantive discussion would focus on whether Meta's Muse agent does indeed have a memory feature, whether the user's request to 'never do this again' triggers it, and how good their Muse model and harness is at following such instructions.
Here I expect factual discussion rather than misleading statements that suggest there was no way for the Muse assistant to follow an instruction never to do something again.
Vague arguments that such instructions are not deterministic are uninteresting, because it is obvious.
