While this is even more true for consoles, the difference is in a specific purpose vs a general purpose. General purpose platforms that become overly closed have roundly been rejected or been forced to open up: Carterfone, AOL, Windows, carrier locked phones, etc.. even iOS itself didn't allow apps at first and now does. Closed platforms for a specific purpose like consoles, kindles, rokus, etc.. do a bit better because they are 1) more likely to have competitors, and 2) have more limited impact from being specific purpose platforms, though are still capable of maintaining monopolies/duopolies. The phone market is a iOS/Android duopoly, and both are being forced to open up more. Hardly surprising.
