Are social games really 'evil'?

In a recent interview with PC Gamer, game developer Jonathan Blow was asked whether he though social games are "evil." The Braid creator responded with an emphatic, "Yes. Absolutely." Currently working on his second major release, The Witness, the independent game designer has spoken choice words about the genre in the past. But this is the first time Blow has associated social games with such a Biblical term as evil. His argument is that by design social games invade your free time as a whole by stringing you along to the next object or feature that you want. But does this make social games evil?
