It's good to eat sans salt on bbq with your desired (typically salty) toppings.
I know people salt the patty while cooking, but the topic at hand is Beyond and their patties.
The whole "salt" angle is bikeshedding - no one advocated Beyond for salt, they pick it for all of the other health benefits (fats, cholesterol)
Nothing whatsoever is stopping Beyond from removing salt and allowing people to salt their own burgers, as they already do.
What matters is not so much the natural form, it is how the product is typically consumed.
But of course I see your point that with home made meat-based patties, you are in control of how much salt you want to add, while with factory made patties, you have to take what you get, it's typically not possible to "take away" salt. Mind you, though, the latter argument holds for both plant-based and meat-based factory-made patties.
