Reddit is going to come up with an excuse to shut this down too, because any app that remains is still going to be lightyears ahead of the official app, and everyone will go there, and the devs have neither the means nor the obligation to force people to mail them proof that they're blind.
If Reddit is savvy, they'll give it six months for this furor to die down before they start to move in. A bunch of little fires separated by a span of time are easier to deal with than a giant fire happening all at once. But since this is spez, the second the API calls from RedReader get above whatever arbitrary dipshit threshold he's set in his mind, he's going to throw another fit. Which will be probably less than two weeks into July.
