Soy is actually a miracle food that has been slandered to hide its benefits. Non-gmo organic, of course. Anything full of Monsanto is bad for you. But the whole "it makes men grow boobs" thing was a lie, just like when they said cannabis makes you rape people and commit suicide in the 1950s.
That said, most vegan patties don't use soy anyway. I don't know what's in that one, so maybe it's got soybean protein or something.
Peas and beans are great for making burger patties. The flavour and texture can be made to match flesh if so desired, and of course they are loaded with proteins.
