Exactly.
I remember back in the UK, once upon a time, people would spend all evening in the pub drinking pint after pint of lager then at 'chucking-out time' heading for the nearest bad Chinese restaurant where they could get more beer. They would wake up the next morning complaining they had headaches and were dehydrated from that Chinese MFG stuff, totally forgetting the gallon plus of cheap lager they had drunk.
Also, if anyone does feel discomfort after eating Chinese, that is no proof MSG is to blame.
Billions of people eat MSG every day with no ill effects. I've only ever met one person in China who claims an intolerance, but she claims intolerance to everything!
