I'm a Bolt driver with the opposite experience- every charger around me is a ChargePoint, EVGo, or Electrify America. This isn't generally true across the country of course, but I generally drive in the Denver/Boulder, Colorado area which is somewhere I would expect considerable EV infrastructure. Some do have a single Tesla connector among a set of several J1772 connectors, although most commonly I see several J1772 connectors and one for Nissan Leafs.
