No yeah they totally deserved that. Though matchmaking should not be forced, it's really the only excuse they have in this situation. Otherwise if they don't want to play then don't. I do the same thing you did, even when they aren't together and it's just one. I don't care if they report me either. It shouldn't be designed so naively, people are terrible. Pretty much why I don't care so much for matchmaking in endgame activities. Sure enough it'll simplify group making, but it won't keep people from being insufferable.
