To be fair, this is kind of neat-- it means the Tesla system fails "open" and, as long as there's power at the supercharger station (and all the electronics work, of course), the car will charge. I had some anxiety the first time or two I used a supercharger-- "what if it doesn't work?" -- but so far, that's been completely unfounded. When it 'fails', you get a free charge! I once found a supercharger that said "limited service" which concerned me. All it actually meant was, it charged at 75kW instead of 150. And my charge was free.

This sounds like it creates the right incentive. Maintain your chargers or pay for free electricity.

If I had an electric car I'd try to figure out the auth protocol, surely software-wise it's possible to pretend that a Tesla is plugged in (worst case is that there's a cryptographically secure key exchange, and someone would have to extract the key from a Tesla).
Hah, an adapter that pretends to be a Tesla that plugs between the supercharger and your car, that would fit in a cyberpunk-ish 2021.

IIRC they use PKI with your keypair bound to your account. So if you own a Tesla and hack it you can pretend another car is that Tesla. You can also hack someone else's car but then they'd have to pay for your charging and that'd probably be stealing or something like that.
Even though the plug is standard, you actually can't charge a non Tesla on a Tesla charger because the charger only accepts Tesla. Recently it has been possible to charge cars from other brands for free during a few days in Germany, some say it was a bug, some other say it was a trial.
Also unless it has changed recently, in the Tesla ecosystem the car is connected to internet and reporting the consumption to the paiement system, not the charger. This is not standard and Tesla would have to put some 4G/5G network equipment in their chargers if they have to support cars from other brands.
They may be required at some point in Europe.
The Nissan Leaf uses a Chademo plug which is another standard, more common in Japan and it's very unlikely to charge on a Tesla charger ever, unless someone hacks an adapter.
