"In order for innovation to happen, a bunch of things that aren't happening on closed platforms need to occur. Valve wouldn't exist today without the PC, or Epic, or Zynga, or Google. They all wouldn't have existed without the openness of the platform. There's a strong tempation to close the platform, because they look at what they can accomplish when they limit the competitors' access to theÂ platform, and they say 'That's really exciting.'"
