I agree here. Also myfitnesspal doesn't let you easily correct things for being wrong; case in point many products list only the calories for something, and not the macros/nutrients. I often search for something as a proxy for what I made myself, so don't have the stats, but do know it doesn't have 0g protein, 0g fat, and 0g carbs.
Basically it doesn't seem to want to help you flag things to make it better. A collaborative enterprise would.
