Anything short of a legal document setting out which rights are waived and which are reserved, and under what circumstances, is just PR. No company is going to use a Tesla-patented technology without that guarantee.

Well, step 1 is PR telling the world they can do what they thought they couldn't - use Tesla's patents for free. I'm sure lawyers are busily writing suitable legal agreements as we type, just to clarify obvious concerns. Without that PR, few would be asking permission.
