This might be true were it not for the fact that Tesla is offering the HPWC's to hotels for free, and in some instances Tesla pays for the installation as well. The property owner only pays for the electricity. I don't know for certain, but I imagine that Tesla's offer is contingent upon the hotel not charging Tesla owners for the use of the HPWC, although they might be able to limit it to hotel guests.
I agree. No one is offering free J1772 chargers to destinations. Tesla has an existing product, the HPWC, and they are giving them away to destinations. No other EV manufacturer is doing anything like that. I don't want Tesla to expend resources to develop a J1772 charging station and give that away. If the other EV manufacturers really wanted to make their customers lives easier they would design a J1772 adaptor that works with a HPWC. But other EV manufacturers by and large just want to build compliance vehicles. So until they get serious, it's their problem to deal with.
