OK but I say you're being obsessively pedantic about this specific word "meat". Perhaps English is not your native language but the word "meat" is a very generic word indeed. Unlike the geographic controlled-origin terms, no group is harmed financially when the word "meat" is - in your view - abused. That argument is a non-issue. English is full of ambiguous generic terms which cause no comprehension problems because the context makes clear what they are. No carnivore is going to be tripping up on seitan burgers. They will be labelled as seitan, just as beef burgers are labelled as entrecote or rump or whatever. The word "meat" will probably not even appear on the packet. It's a non-issue.
