The display the author doesn't like is a specific model Dell QD-OLED with a sub pixel arrangement that causes a fringe above / below text.
There are macro screenshots that reveal the sub pixel details of a preferred LCD compared the disliked Dell OLED, and it's easy to agree with the author's discontentment.
But the categorical complaint about "OLED" is an over generalization.
Treat the report as a warning to investigate the sub pixel characteristics of any monitor you may be considering.
Yeah, I've had subpixel antialiasing disabled for a long time, since before my first OLED; I prefer grayscale antialiasing.
While the author's complaint is perfectly valid, in practice the advantages of even current OLEDs - for me - far outweigh any disadvantages due to subpixel layout fringing and everything else. Even for programming, the lack of backlight and resulting infinite contrast makes such a huge difference in my day to day life that I refuse to use a non-OLED monitor anymore for any purpose whatsoever. Heck it could be half the DPI and I'd still go for OLED anytime.
The only reason LCDs still exist is price, nothing else.
It’s in fact most, if not all of the PC display OLEDs on the market today because they almost all use non standard subpixel arrangements, but will change soon with the introduction of newer generation panels.

It’s really not, given again we are talking about the majority of PC OLEDs in production today having subpixel layouts that cause issues for users with text rendering.
I'd been having an issue with a vertical dark bar during wakeup for a few months, but it'd go away after the whole screen came up so I pushed off opening a case. Then one day the whole thing started having problems.
