We could say Twitter was instrumental in organizing human rights causes in the Middle East and is now important to the human race as a communication tool; that said, if Twitter doesn't implement a feature that you want, you don't get to redesign Twitter at your whim and call it "New Twitter". You don't have a "moral claim" to write an open letter to @jack telling him why you're moving on without him.
You instead, like all rational people, design a competing service and let your work stand on its own.
