Sweetmeat and coconut meat are both not animal muscle, while fish, which is animal muscle, is not meat. Distinctions like 'meat' and 'milk' (and pretty much any culinary term) take on meaning according to our conventions and dietary norms, and if plant-based meat grows to fit the same dietary niche as animal meat, people will call them the same thing.

All meat is plant based :)

I only can interpret that label because I'm now cynically familiar with the deceptive advertising practices currently used. But, to someone not used to how advertisers try to make one thing seem to be another, saying 'beyond meat' is 'plant based' does not communicate this thing is just a bunch of vegetables.

Yes, I'd prefer my products to be clearly labeled, but that's just a personal oddity, I know.

Less so. At least those names, though oxymorons, do contain the actual product being sold.
