On a personal level, it is probably best to be happy with your decision, move on and don't be bothered with what other people are doing. As for federated social networks, without a dictator running things it would rapidly degenerate into spam - I work on fb virals and I could think of many ways to abuse a federated setup for profit if I felt like it. So for that reason alone I don't see it happening, but there are others too.
