Dealing with nasty user feedback like this is one of the most painful parts of running a product. It still amazes me how many people refuse to consider the fact that there are humans on the other end of the computer. Instead, a lot of these arguments turn into accusatory conspiracy theory threads, as though things changing is a sign of some "secret plan". Is it that hard to believe that a product team is just trying their darndest to create the best product they can? Sometimes they'll get it right, and sometimes they won't, but constructive feedback always goes further than angry fist shaking. There's something about feedback for products on the internet that brings out extreme paranoia in people, and I don't get why that is.
