I've seen that "technique" used quite often. It's easy to construct a
"Totschlagargument" [German], an argument that can't be refuted. It's important
to identify these and point out that they are used. It can help to get the other
party to realize what they are doing.

Replying to @coderbyheart
Example for a Totschlagargument is: "People are not satisfied with X!" "But you
only get negative comments, most people are happy with it so they don't
complain. Therefore X is fine.". This is impossible to refute because it uses an
unlimited amount of positive feedback for X.
