Pure soy doesn't taste too good in my experience. I tend to prep the dehydrated stuff I get with (ironically) soy sauce, which is quite salty, plus whatever else the recipe I'm using the soy in calls for. In the case of soy burgers, that mince needs some binding agent.
It's odd, as I generally agree that "pure soya" doesn't taste that great, but I do prefer the taste of edamame beans which are just young soybeans. Products like tofu generally need more flavour adding to it - and I personally like tofu and eat it fairly regularly, so I'm not biased against it.
Also, I like the taste of Natto (soybeans fermented in straw) though that's generally thought of as an acquired taste.
