I doubt it's any kind of conspiracy or anything. To me, it's like most other synthesized foods... you're eating something that wasn't intended by nature, so there is going to be a chance that it doesn't react well with your body. The fact that it was the accidental result of someone trying to create a drug to fight ulcers doesn't really speak much for it being a good idea for healthy people to take in high doses (or even multiple small doses). It's like if you took Oxycontin and found out it tastes like chicken, then decided to use it like bouillon. Never mind that it wasn't intended to be a food additive, it tastes good so let's market it as such!
