As I said, it is right for physical temperature.
The Kelvin scale is specifically for colour temperature, which is not the same, with “warmer” colours given lower numbers and “cooler” colours given higher numbers. That is how is has always been and to state that it is “wrong” is to confuse the issue.
If you really want an ascending scale for the “warmth” of light, you can always use MIREDs, which is a reciprocal scale to Kelvin - that is if you can find anyone else who can be bothered to learn that system.
Once again, this is conflating the idea of physical temperature with colour temperature - the two cannot be compared
