I think the thing I hate the most about 3rd party chargers is how many charger per the minute rather than kilowatt. Their shitty charger can put out half the rated throughput but they still make the same money

That is largely a function of state rules that make it hard to charge $/KWh without falling under a different (and often onerous) set of regulations. It doesn't have to be super expensive this way, though. Both Tesla and Electrify America offer decent per minute rates here. EVGo here is over twice as expensive and tends to underperform on charge rate, depending on the state of charge. Or at least I hope it improves at higher charge levels... I think it is amperage limited like CHAdeMO.

You can't effectively do that since the spot price per kilowatt-hour changes drastically from every minute. The per minute pricing reflects that, so you don't have to worry about fluctuating prices. It also add a "tax" for "hogging" the chargers, as the rate of which you're able to charge drops significantly after some time. You're probably being gauged compared to the true cost per kilowatt-hour, but that just mean there's room for more competition.

  I understand that, but I'll take an average even at the benefit of the distributor rather than per minute pricing. Imagine if we had to pay for gas by per second.

Per-minute charging prevents people with crappy cars (PHEV, older EV) from hogging HVDC charging locations. They'll do it once, see the bill and never do it again. Basically if your PHEV can only take in like 15kW from a charger it's not cost-effective to charge from a HVDC charger that costs 80 cents a minute. But if your car can get 300kW from the same charger, it becomes useful again.
