Get people on board first. Lock it down once it's too late and everyone is invested.
If, say, the iPad or iPhone had gone this route (started off as open as Android and then became locked down) you might have a point. But they didn't, they started off restricted and have only (gradually, and to a limited degree) been opened up.
Examples? Been using the Mac for 15 years and haven't observed this myself. iOS was more or less locked down from go, but they never did some kind of bait-and-switch.
