I wouldn't consider it collusion, exactly, since you're apparently not planning on getting anything for it. It's still awfully bad poker etiquette (at a minimum) to reveal your hole cards during play (don't know if it's necessarily against the rules for a specific site, and don't especially feel like checking).

I'd probably be annoyed at the first hand chatter, too, even though in that case you didn't actually reveal your hand. Not annoyed enough to complain to anyone, though (and I assume you're posting this because someone at the table whined at some point).
