Apple had/has that business plan. The difference is that they had a unique product. As other brands produce "mirrorless" models, Sony will either wake up or shrivel and die. Even Apple has opened the door a little (running Windows on their PCs). They have the money to buy up composition like Microsoft did for a while and troll for patents. It's what keeps Apple alive.

As long as they refuse to let other companies make things for their wacky designs they will fail. I need an off camera flash cord for my Sony NEX. Sony won't make one, and they won't let anyone else make one either (they have patent control on their wacky flash interface). My next compact camera will not be a Sony.
