So by this logic Tesla should be banned from all Electrify America chargers because Telsas can only charge at 50 to 70 kW with a CHAdeMO or CCS adapter. And older Model Ss should be banned from Tesla's network because they can't charge at 150 kW. Is that your proposal?
Charging a 50kW max car from a 350kW charger is like driving a go-cart on a freeway. Yes, you can do it. Should you? Probably not. Will other people be annoyed by you? Definitely.
