They already allow Google Apps admins to control whether Google Labs or experiments are available, not to mention specific controls about the various other apps. This could be handled exactly the same way to allow domain admins to control whether users can use Inbox.

Why not? They could just make it opt-in through the admin console like almost everything else that companies might not need/want (Youtube, G+).

This is opposite from the way car companies do it.

They test new ideas and features on the luxury brands and then roll them out to the mass market brands later at lower prices.
