it was so annoying to suffer the fools who loudly complained about tesla roadblocking a universal charger while ignoring the fact that NACS was way better than the alternatives
Tesla's charger was proprietary so other manufacturers couldn't use it. Meanwhile CCS is an open standard that anyone can use.
What's changed is that last year Tesla decided to publish an open standard. Now that other manufacturers can use the plug, they gave agreed to use Tesla's physical plug design, but with the CCS signaling protocol.
So NACS going forward is more of a new hybrid of the two rather than a switch to Tesla's existing charger. One of the outcomes is that cars equipped with CCS will be able to use NACS with a simple adapter.
Why not use Tesla's signaling protocol? I don't know the details. Maybe Tesla isn't ready or able to create an open standard for that part. Or maybe other manufacturers want to keep the signalling they have to keep adapters simple. In any case only one vehicle and charging station manufacturer (Tesla) will have to make updates on the software side, and to people who don't know the difference between the plug and the software it'll look like Tesla won the charger war.
Sure, when it became an accesible standard it was better. A better technical solution that couldn't actually be used by other manufacturers is not an actual solution, so until Tesla actually put up people were right to complain (similarly about Tesla's chargers not supporting other vehicles). For a long time Tesla talked a big talk about pushing EVs as a whole forward while doing their very best to fragment the charging ecosystem as much as they could. It was very right to complain about that, it's probably part of why they have actually brought their actions in line with their words.

For example, if your car has the wrong date and time set, then the TLS connection won't establish and you won't be able to charge.
