Why does nobody talk about using the wrong wire nuts for a dimmer switch

I spent 3 years jamming the same purple wire nuts onto every switch I installed, until last month a senior guy saw me doing it and laughed. He said those are meant for aluminum wire, not copper. Have you ever used the wrong connector for years without knowing it?

Wait, you spent three years using purple wire nuts on copper? Those are literally made for aluminum connections, I can't believe nobody caught that sooner.

Man, I've been using purple nuts on copper for like 4 years now and never had a single callback or issue, so what's the big deal? @olivers28, I bet half the guys claiming they're "only for aluminum" couldn't even tell the difference in a blind test.
