Others can fix it too and they have. See:

I use MacType and it works really well. You can tune many more things than with ClearType.
I've tried MacType before but sadly it came with significant slow down in many applications, lists would lag while scrolling, etc.
It's really annoying because all I really want is to disable ClearType on my primary high DPI monitor while keeping it with default settings for my two side monitors, but Windows does not let you configure it per monitor.
Same here, running MacType/Windows on a 65" LG 4k OLED C5 TV with 100% scaling as my main display for all kind of stuff incl. coding. But i must admit that fonts on Linux looks noticeable better out of the box and MacType/Windows does not apply to all applications. E.g. for LibreOffice i had to change the rendering engine(disable skia) under options and on PDFGear MacType does not apply at all.
Anyway, OLED is great, I'm sitting 2 arm length away from the panel.
People complaining are probably Gen.Z that never sat in-front of an ol' CRT in the 90s and are spoiled by smartphones running 4k on minuscule 7" displays with 460ppi.
