Yeah, well that’s a cultural thing really. Celcius and fahrenheit scales are both quite arbitrary. The kelvin scale uses absolute zero, which totally makes sense, but the other fixed point is pretty arbitrary when you think of it. The fahrenheit scale makes sense for the human experience of weather, while the celcius scale makes sense for generally life on Earth where water plays an important role. Neither of them are particularly universal, and they both suck in their unique ways.

Life Pro Tip: If you take the piss out of two units at the same time, you can make everyone equally angry.
I don’t really use the Fahrenheit scale for anything, but when I bump into it, I prefer to think of those values as: 0°F is a cold winter and 100°F is a hot summer weather. Makes sense for the human experience, which makes it a very practical unit. The original definition was more technical than that, but it was also severely limited by the technology at the time, so it had some flaws.
You also have to look at these units in the proper historical context. Measurements were a complete mess, so having at least something that sort of makes some sense and is somewhat repeatable, is a clear improvement. Both, Fahrenheit and Celcius scales totally addressed those concerns, and that makes them both good enough. Absolute zero and plank temperature weren’t even known back then, so what can you expect.
When it comes to using these units in serious scientific and engineering applications, you run into problems, but the kelvin scale addresses those pretty well. It’s not exactly elegant, but at least it’s functional. Because of historical baggage, we’re pretty much stuck with these units, but it could be worse.
