I'm pissed at HOW they did it. Without an ounce of respect for the user base. They could have made it affordable and turned a profit out of 3rd party apps, they could have been more civil on the communications, they could have explained the problem and asked suggestions, even if they had no intentions on doing something else.
But they choosed a huge FU, not only to it's end users, but to people that were trying to make reddit a better place, either at barely a profit, or with volunteer work.
