If the likes of EA and EVGO thought it was challenging to make money running chargers, boy the pressure will be on now. They thought they had a captive audience and POOF... their customers have an alternative.
I'm going to sound terrible here, but bear with my conspiratorial thoughts. The OEMs waited until Tesla committed to NACS in 2011 before ratifying an entirely different plug in 2013. They tried to hobble tesla by waiting until Musk went left and then all went right. Further, they've hobbled consumers by creating unreliable chargers. There's apart of me that says this was done with a nod and wink from the OEMs to scare people away from EVs. Call it a loss leader for VW... give a half hearted effort to create something that will ensure the sale of ICE cars for decades.
FWIW, the original J1772 included a DC mode where the AC pins were to be used for DC at up to 80amps. They could have simply used the same pin sizes presently in the CCS DC plug in the J1772 housing but didn't. When Tesla created the NACS standard they were just running with the original idea of the J1772.
CCS was proposed in 2011. It was ratified in 2012, first prototypes in 2012, and the first public CCS charger was opened in mid 2013.
Initial work was only up to 200A though, less than Tesla pulled in its v2 in early 2013.
No conspiracy.
Tesla didn't initially adopt CCS because Tesla was moving faster and higher than the rest of the industry.
I don't think it sought to be proprietary.
The choice of modified Type 2 for Europe helped when legislation forced it to move to CCS Type 2, as it could switch the DCFC without switching all the EVSEs.
As for charge port location, there is no one location to rule them all.
Front center is the most flexible location as it's RHD/LHD agnostic and supports charging at parallel parking.
From LHD thinking, right-side allows for passenger-side parallel parking.
Side is also cleaner than back or front and is less likely to be damaged in a collision.
Driver-side offers the best potential convenience for home-charging as there's always a driver, but depending on how you park at home and where the charger is mounted, it's not necessarily the best for everyone with off-street parking.
I'd like to think that eventually you'd be able to choose between left and right locations.
