If you or a friend has a known sensitivity to it, then by all means delete it.
Having said that, lots of folks who say they are sensitive may not really be, as MSG is found in so many processed food products, and it's not always listed as MSG on the label. If your friend eats processed foods of any kind, I guarantee they're eating MSG in one form or another.
MSG pumps-up the flavor of anything to which it's added, so I do think that removing it from BRITU diminishes the flavor somewhat.
