I sent an email to Tesla's destination charging dept asking
I am aware that 3rd party vendors of Tesla -> J1772 adapters are available for purchase.
What is Tesla's position regarding use of these adapters at destination chargers provided by Tesla to businesses ?
Thank you for reaching out. Tesla does not support any 3rd party products that interface with our equipment and if something does not work properly, there’s nothing we can do from a service perspective to assist. Since some non-Tesla EVs to 20kW and the popularly-sold adapter cannot limit the current to 50A (which is its max), there’s a high likelihood that the adapter will melt if used it on a station outputting more than 50A, which is a high percentage of our locations with Wall Connectors, as our stations have an 80A output and most Destination Charging sites have multiple stations sharing 100A breakers.
Beyond this, it’s worth noting that the majority of our Destination Charging locations have some form of J1772 charging available alongside of our Wall Connectors that was provided by our program. These range from GE, Clipper Creek, and even some Tesla-branded J1772 stations. This has been a good faith offering that we’ve made with most host properties to allow them to serve all EVs, not just Tesla vehicles. The property at which these stations are installed are owned by the property and they also pay for the electricity. The stipulation of the program is that charging is to be free for paying customers of said business, though some properties are offering free charging to the public; it’s their choice to make. We recommend utilizing Plugshare to verify sites with J1772 available.
We have also started deploying Wall Connectors that are Tesla-only, meaning if the units do not ‘read’ a Tesla vehicle on the other end, it will not charge, and the adapter would be rendered useless.
If you do choose to visit a Destination Charging location, we strongly urge that you opt to use any available J1772 station(s) that we’ve provided and to leave the Tesla Wall Connectors available for Tesla drivers first and foremost. If the Wall Connectors there are on any breaker higher than 50A (which is the strong majority) and don’t happen to be Tesla-only, it’s likely that these adapters would melt and cause significant damage to the adapter, Wall Connector, and possibly even the vehicle.

I take this answer to mean, amongst other things, that Tony's assertion that his hack adapter is "vetted" by Tesla is hogwash and is false advertising. My next step is to inform Tesla and the owner of this forum of his posts and advertising.
