@Vamp898 Of course they do that in part because of their competition.
But it turns out, other than the other console guys and Apple? Nobody does what Sony does. Because it's actually not needed!
They still want customers to stay there, they want their technology to stay there, and they want the content to be under their control.
They can't understand people choosing Sony *and* something else.
And they can compete as a hardware company by building hardware the first and the best. That's it.
