It's sort of neutral that there's more than one manufacturer of the other chargers, if the chargers work well with vehicles it doesn't matter if they come from 15 factories or 2.
Tesla clearly has a lead. My point is that it is unlikely to be durable.

“Electrify America currently uses units made by ABB, BTC, Signet, and Efacec. Every time they have a software or hardware update, it has to be done on all four brands, and they don't always all work the same afterward. Fitezek has to work out the kinks with all four partners and they all respond on different timelines. I could see that this was clearly a pain point for him.”
Long term? While I don't feel confident hazarding a guess when the ICE–EV inflection point will occur, I expect that inflection point to be marked by a series of corporate collapses as the transition (or indeed the failure to transition) ultimately bankrupts them.
