Gagging developers for writing code seems way beyond "legality" to me. They should be able to at least say "I'm being sued for developing Popcorn Time". If your government is gagging you from saying even that...then something has gone terribly wrong somewhere, and yes that does seem like a totalitarian tool when used like that.
There's all manner of totalitarianism-lite in the US. This is not likely one of them. Its a safer bet that this was handled directly by mail/phone/email without involving an actual court. Legal threat under possibly enforceable law does not equal government action. We don't need to blame the government for this to be a bad thing.
