I am not sure you can make an argument of "other people are doing it too". Lots of people do things that it is not in their interest (ex: smoking, to pick the easy one).
As others mentioned, I did not have the negative connotation related to the word prism either, but not sure how could one check that anyhow. It is not like I was not surprised these years about what some other people think, so who knows... Maybe someone with experience in marketing could explain how it is done.
