Threatening to leave because you want something on a service to be left unchaged is not equivalent to leaving a service because there's a newer, better service

Threatening to leave because you want something on a service to be left unchaged is not equivalent to leaving a service because there's a newer, better service available. If site designers listened to everyone who gripes when a feature changes, they'd never change anything much, and inevitably would end up losing out to someone who comes along with a better product. That's much closer to what happened with MySpace - they failed to innovate, and got overtaken by FB.
