This basically seems to be a case of Tesla truly opening up their connector standard, marrying it with the existing standardized CCS communications instead of their previous proprietary communications, and using the carrot of access to their charging network to get other manufacturers onboard for the North American market.

There are some governmental pressures to use interoperable connectors used by multiple brands if you want to be eligible for federal infrastructure EV charger funding. Tesla is making themselves eligible for this funding, making sure they won't be legislated into changing all of their charge connectors to CCS1 in the future, and gaining new customers to improve profitability of their charger network.

Tesla is by far the fastest growing DC charging provider in the US, on track to build over 500 stations this year with each station being 8+ chargers, some with 40 or more chargers.
