You seem to not understand how a non-profit works. It's not a "lose-money" company, it's a "non-profit" company. Tesla needs to pay for the capital costs of the chargers somehow, if they charge the going rate for electricity they will NEVER pay off the supercharger...
Not to mention his own source disproves his original claim that SCs now cost as much as "gas guzzlers"
If national SC average is 28 cents per kwh a full charge of a model 3 (310 miles) costs $21.
A gas guzzlers (subject to the tax of the same name) is defined as a vehicle getting less than 12.5 mpg combined under EPA testing.
Let's use exactly 12.5 mpg though to be as generous as possible to his claim.
So 310 miles would require 24.8 gallons of gasoline.
Average gasoline price in the US right now is $2.273 per AAA.
That's $56.37 to drive the same distance the Model 3 will go with $21 of supercharging.
Not only is the Tesla cheaper, it's almost 3 times cheaper.
(and this ignores the fact most EVs will be using much cheaper home charging for anything other than road trips- and the fact many gas guzzlers require premium fuel which costs significantly more)
