C'mon! There should have been a standardized plug right from the beginning of this mess!

Do you see different nozzles on gas pumps that won't fit in your car? NO!!
Some demwit needs to get this figured out, and I'd say pretty soon.
Tesla tried to give their plug to the ANSI/SAE committee but they wouldn't take it. Committee still didn't see the need for DC charging, thought everyone would be happy with J1772 on 120V outlets.
Tesla wanted both AC and DC on the same pins. At the time there was J1772 for AC and CHAdeMO for DC. CHAdeMO is a big ugly DC-only plug only used on Nissan LEAF. The CCS plug wasn't invented yet.
The resistance to putting AC and DC on the same pins is that a DC switch costs more, must be much bigger than a comparable AC switch. Tesla's argument was that eventually everyone will want access to fast DC charging, and the DC will not be placed on the cable until after the EVSE has established proper connection with the EV asking for DC.
Forced to commit to a design in order to ship Model S in 2012, Tesla went with their own elegant and simple plug.
Tesla speaks J1772 on their plug for L1/L2 AC charging. Many have purchased Tesla Wall Connectors and Mobile Connectors, cut the Tesla plug off to be replaced with a J1772. The Tesla adapter to use a J1772 EVSE is nothing but plastic and electrical contacts.
In later years the ANSI/SAE committee invented the CCS plug, placing additional DC contacts off to the side of the J1772 plug.
In the early years Tesla openly offered to open their Supercharger network to other manufacturers. The stipulation was the other manufacturers had to participate on equal terms. That meant the EV had to have comparable range and charge at comparable rates as a Tesla. The plan was to build Superchargers every 125 miles so the EV had to be able to span one Supercharger to the next. That Superchargers are not gas stations for your daily needs but serve to facilitate travel.
