The connectors between the North American version of CCS (CCS Type 1) and the European version (CCS Type 2) are different. The NA connector had some clear disadvantages, mainly in its locking mechanism.

The NACS standard uses CCS communication protocols. So it's as related to European CCS as CCS Type 1 was.

And in Europe Tesla uses CCS Type 2 without any discernible issues. In fact the Tesla/NACS connector would be a significant downgrade for the European market because Europe frequently uses 3-phase AC for charging and Tesla's connector does not have the pins to support that.

Tesla opening their connector last year in the US, branding it as the North America charging standard, and working with other manufacturers to get their support was driven by government intervention, namely the Infrastructure Bill which requires use of a charging connector used by multiple brands to be eligible for federal funding to build chargers.

I think Tesla's connector is great but you're missing a lot of context in your story.
