I might be completely wrong on this subject, but it seems to me that people who are ICE-ing are just trying to get attention. Look at the photo in the first post - all are driving trucks. It could be a coincident but maybe it is a telling sign.
I can't imagine this behavior tolerated if Tesla charging stations had a convenience store with an attendant and a business to run. There would be a police on site and towing trucks real fast.
Imagine a flip scenario where a regular gas station would suddenly have electric cars parking in front of the pumps, preventing people from getting gasoline. There would be uproar like no other. But most Tesla charging stations now are tucked away and unattended, which makes this behavior a nuisance for most people but a major pain for Tesla owners.
Some people are parking the progress, while others are driving it into the future 😜
