I find this suspicion suspicious. I know that some people are melodramatic about it, but why can't people just have their food without gluten if they don't want it? Nobody ever backlashed against the anti-MSG thing, and that was arguably way dumber.

On the other hand, I have heard that this has resulted in lowering of standards for handling gluten, and people who are severely allergic are being exposed to small amounts, while people without celiac don't notice those small amounts. So, that's bad.
