No, they don't have the right to shit. They are recording something they don't have the legal right to and therefore have no right being elitist assholes about it.
For starters, the Dresden Dolls have given permission for fans to record their shows. They've also given permission to distribute them, but they haven't made a demand of that part of it. There's no obligation to do anything but give the band a copy of the show when you've taped it. After that, if you want to share it with other people no matter how limited or unlimited that is, it's up to the taper. So, it's not illegal.
Hell, it's probably not even illegal for artists that don't give permission. Most states don't have a law explicitly saying it is illegal and it hasn't been challenged in courts yet for any cases that don't involve someone selling the recordings for a profit. So, there's only a gray area there, not a fully defined legal or illegal stance for the most part.
As for the right to be an elitist asshole, that's up to your perspective I suppose. Once you've spent a few thousand dollars on recording equipment, get to the shows before everyone else in order to get the best spot in the room to tape from, have to deal with people who are unintentionally doing their best to ruin the recording, and then come home to clean it up and make the recording sound as good as possible... only to MAYBE get a few "thanks!" from a small percentage of the people who listen to it? I dunno, mabye it's just me but I can understand why some people wouldn't be terribly thrilled to make sure you get a copy of their recordings. It's a lot more involvement than most people even care to realize, you've got the hostility and ignorance of a LOT of people in your way from the start... It's a little difficult to not get at least a little pissed off at the people who don't tape shows trying to dictate what you should be doing all the time.
