If Elon Musk would only be interested in more and more money, then the Superchargers would never have been free at all. And then we would have been paying a certain amount each time when we would use the Supercharger. Just like we now already do at the gas station every week/month.
On the contrary, Elon Musk decided to make the best possible deal for us (pay only once at front, and then charge for free). I bet that none of the gas stations on this planet will ever do us this favour. Therefore, we should show some appreciation. And not act like children who do not get their new toy exatly on time.
Welcome to the entitled society.
What I find strange is how Elon must have understood that the SC plan was completely bogus and that some people would have such over the top reactions. Maybe it was just a communications SNAFU but even July is looking like a stretch - there are SC locations (OK, approximate locations) that don't appear to have even been started.
