There's two reasons to leave a service, you can make a political statement - you leave because you disagree with their politics and you don't want to endorse them by associating with them. That's a legitimate reason to leave (although extremely often people declare they're doing this and then don't). But it's also perfectly legitimate to say "I'm leaving because the product got worse". It's sort of orthogonal to the political reason. Some people don't buy from Nestle because of Nestle's terrible track record, but I don't buy from Nestle because they're not selling anything I want. The second reason, generally is the thing that actually kills services. Digg didn't die because it conducted business unethically, it died because they fucked up the product, and that's what's happening here.
