Stupid reason to report someone

[Mimilu]

it does when one side says change your ways or stop playing and the other side lets them play as they like.

No it doesn't because, hopefully, a friend wouldn't tell you to change your ways or stop playing (unless you're doing that badly or are doing something unhealthy).
As for getting people from the PF, well, they agreed to come with you, so they can't really complain because they chose to come... Plus, you can leave a dungeon if it was in a pre-made group without getting a penalty, so they don't have too much to worry about.
