What open standard? CCS is neither open nor a very well defined standard. Think patents, licensing, and lot's of car and charger specific behavior and weirdness, endless software glitches, etc. Design by committee stuff that the likes of VW, Mercedes, etc. came up with years ago. Let's just say it's not very good.
It's why non Tesla chargers are such a compatibility mess. There are a few emerging standards like plug & charge and a mess of ISO and other specifications. So, things are slowly improving but there are still lots of issues with cars and chargers not being compatible with each other, weird payment processes and complexity, enormous testing overhead to deal with all the silly hacks, workarounds, bugs, etc. CCS is a bit of a train wreck as a standard and it's a bit user hostile. And very much a work in progress.
The Tesla ecosystem predates all of that and is un-apologetically a Tesla ecosystem that has been running smoothly for many years that has none of those issues. While other vendors insisted EVs were a fad, Tesla actually invested in lots of chargers which is why they dominate the market.
The Tesla charging experience is best in class in this industry. It is a standard in its own right as well. Tesla positions NACS as an alternative to CCS. And like CCS, you can license it in order to use it and it is well specified. Ford and GM just chose to license NACS in addition to CCS to enable a better charging experience for their users. Nothing wrong with that. I'd say, more vendors will probably do this and that would effectively make it an industry standard just like CCS is. All an industry standard is is different companies agreeing on some specifications and signing licensing agreements with each other.
I think instead of governments dictating half broken specifications as standards or endorsing this or that consortium, it's better to just let the industry sort things out by itself.
