I'm going to say there could be more to the story. The unplug guy is pretty polite. I don't see 'all the chargers' from the footage.
You must live really far way from that charger with a 100D to need to plug in overnight or longer to an L2 charge. The video as at 3:36am when City Hall is not open.
There used to be 2 L2 stations, but now only one. Drivers report there is only 1 connection working. If the 100D is parked there constantly to save a couple of dollars, that is the world's cheapest and most self-centered bastages in the area, especially if he doesn't use the building every time he charges. Not to say that's the case. But who plugs a long range EV into a low-speed city hall charger at 3:30 am if they live in the area?
Possible guess? It's a city hall worker who needs the range and finds the same Tesla there every morning with dew on the windshield. Possibly has seen them use a second car and assistant to use the plug.
I liken it to our dumpsters outside. I pay for it, but it is not locked. People from the nearby houses would come and dump their large trash. The Sheriff says there is nothing they can do about it unless a Sheriff witnesses the dumping, even with no trespassing signs. The people doing know they are cheap aholes (you can rent a dumpster or call for large pickup) but figures they will just stab their neighbors in the back for a few pieces of silver.
It's common today, the entire attitude. Me First, Screw You.
