Took me a while to get through this entire thread, but I wanted to read it thoroughly before I responded.
It may not be a popular stance, but I'm going to take a bit of a contrarian view and defend part of the OP's viewpoint -- that this situation is a negative for Tesla, Tesla owners, EVs in general, and the specific driver involved. I'll tell you why.
Perception is the issue here. From the single picture originally posted, there are two things that are factual:
1. The car is a Telsa, an electric vehicle, and it is plugged in and charging.
2. What it is plugged into is not a public charger.
Now, that's all we know. We don't know anything else, including who this driver is, who owns this electrical outlet and it's power, and what the driver's relationship with the outlet owner is. We have no idea whether this charge was an emergency or otherwise.
When you don't know anything, the door is now open to wide interpretation, and people will interpret things to fit their agenda. This is where the problem lies.
Here on the Tesla forum amongst Tesla owners, we can craft many possible scenarios that are legitimate explanations for this scene. It's a brand new Model 3 (paper plates), perhaps the new owner nearly ran his battery dead and needed an emergency charge. Maybe he had permission from someone. There's dozens of legitimate scenarios. For those of us who have a positive view of Tesla, we would love to believe that one of these legitimate explanations is true, even though it is pure speculation that we're inventing out of thin air.
There are others in this world who have a negative view of Tesla. They think Elon is full of hot air, the company gets billions in taxpayer subsidies, and the whole green/efficiency thing is complete BS. They can look at this scene and also create dozens of interpretations where laws are being broken, taxpayer money is being siphoned off, entitled rich owners are taking the city for a ride, etc. Their interpretations are no more rooted in evidence than ours are, but some of these people will take these invented scenarios and exploit them to further their own agenda, whatever it may be.
Somewhere out there is an anti-EV blogger who will take this picture and post it with a clickbait headline of "Another Entitled Tesla Owner Steals Taxpayer Dollars!". He's almost certainly wrong, but the damage will have already been done.
The question is, as Tesla owners, can we be cognizant that there are those out there who vehemently oppose Tesla, and not leave these interpretations up for grabs? If at all possible, maybe we shouldn't give ammunition to the haters.
Perception becomes reality, and appearances matter. Sometimes appearance shouldn't matter, but guess what, it does.
