Plant-based meats =/= plant-based foods
It's also worth looking at one of the big points criticism actually is, which is that it's such a broad label as to not be meaningful. If I lumped candy and apples together for being glucose-containing foods, we'd have a pretty poor understanding of the actual effects of apples. They point to studies on specific categories going differing ways
As a side note, it also tends to only get applied to justify whatever people want to already think. Like adding protein isolate/powder makes something automatically become a high category processed food and yet people are buying protein-XYZ products with protein isolate added to them while being against UPFs
