Yes, they can turn read receipts off.  Becuase many users find it an invasion of privacy and some sites have concerns about legal issues.

But they can't turn delivery receipts off.  

And if an email is read in the preview pane, it may not initiate a read receipt regardless whether the feature is turned off or on.
