That’s all well and good … however the ‘censorship’ of a certain subset of tokens by others still is ‘a thing’ and that ‘thing’, whether you ascribe it to the term fungibility or not, can be defeated by adjusting that protocol as Monero has and Bitcoin has not.
So it’s fine if they want to debate the terminology, but such a debate doesn’t change the reality that there is a fungibility-related problem here.
