This "IACNAP Campaign" is pretty annoying.

Linguistically, language evolves and usage is king, so what you want words to mean (and/or what you were taught that they mean, and/or what they originally meant (assuming you can even chase down the etymology to verify)) has no bearing whatsoever on what they currently mean. There is value in specificity, but there's also value in not "correcting" people when they're using terminology understood by everyone in the conversation.

To whit, McMaster-Carr redirects searches for "pneumatic pistons" to their catalog page for "pneumatic cylinders."
