Yeah I saw all that. But I stand by the original claim (which, let's remember is pretty modest: saying the expense is *comparable *. Not sure why people are so threatened by this) .
And I repeat my invitation for others to supply better information.
I sanity checked the relevance of charging a Mach E at a non Tesla supercharger. I decided it was still relevant. The Wh/mi consumption rates are roughly the same for the Mach-E and the Tesla the OP is asking about: (see fueleconomy.gov citation above)
3rd party chargers like Electrify America aren't crazy more than superchargers.
