EcoTality has clients like the DOE and the air districts. You might want to inform the air districts that the "unilateral" nature of this contract is interfering with their project and preventing them from collecting the data. A contract that respects the EV owner and does not leave the legal door open to the addition of arbitrary terms, like changes in privacy, or adding clauses like payments due from the EV driver to EcoTality.
Yes, the charger is a gift and I sincerely appreciate that, on the other hand, I'm not about to give you a legal blank check in return! Clearly the lawyers have gotten very heavy handed and destroyed the intent of the relationship between the parties. I don't think any of the parties really meant to ask for a legal blank check or understood the ramifications. They probably just blindly modeled it after some credit card contracts or legal boilerplate and never bothered to read the contract from the EV owners point of view.
They don't even specify how they will notify the driver of the change or what constitutes notification. I.e. they send you one email that is caught by your ISPs spam filters which you have no control or visibility over - does that mean you are notified? Or more reasonably, you log into their portal and can select "I accept", maybe if you don't they deny you access to the portal, but at least it's a notification has verifiable receipt by the EV driver. Or update the Blink screen that starts the charge, "please read our new agreement here, and accept it to continue use of this charger. You have 5 more charge sessions to accept the agreement or this charger will be disabled." Of course, the 5 charges, reliably counts down with each charge event.
That notification combined with a reasonable, not a black check legal contract is in the interest of BOTH parties. We read it, see the reasonable terms and protections and accept it so that we get the charger (many of us already have it), and EcoTality and it's clients get the data we all need them to have to roll out EVs.
