I know Josh personally, and consider him a friend. This is not the kind of person he is, however, I know nothing of his business practices so I'm not defending the company in that regard. I am just saying sometimes when you hear something about someone and you think wow that is totally not who they are at all...this is one of those times.
With that said, speaking from a consumer standpoint. I have used their protein, it definitely does not taste like something that was loaded with any extra fat or carbs. I realize it is hard to gauge off-taste alone, but I have had a **** load of whey in my day, and it is obvious with brands with higher fat and carb content in their servings because you can taste it. Bowmar's whey is just not good enough to not be only protein lol.
Perhaps it is their other products like Bob said, it is a lot easier for macro profiles to be off on things like bars and butters.
