I haven't watched the video, and in all honesty, I don't care about those people. I don't even have to watch their video to know that they're just
commoners who know nothing about vintage lighting. Are they saying that LED's don't flicker? If so, that's enough proof that they don't know what
they're talking about. I've seen many, many LED's flickering, whether it be visible flicker, or hertz flicker similar to what we see from magnetic
ballasts. All this talk of headaches... the LED's should be very well known to cause headaches, for numerous reasons, even more than fluorescent.
But, the average person has been brainwashed into thinking that LED's are better... so much to the point where flickering, fails, cheap quality
and atrocious color... all of this gets ignored and sometimes even defended.

Poor quality LEDs flicker just as much as magnetic ballasts fluorescents. Cheap LED bulbs often will have banding.

Also, sometimes people mistake daylight LED bulbs for fluorescents. Another thing that makes no sense is when people say most early CFLs emit a bluish white, when that is not true, as daylight CFLs weren’t even popular in the late 90s to mid 2000s. They couldn’t easily be found in stores. Most CFLs were 2700K for a while, daylight CFLs didn't gain popularity until right before LEDs did too, which was the very late 2000s. Finding a vintage preheat CFL in daylight is an extreme rarity.

Also, it seems like in residential applications, magnetic ballasts were used well into the 2000s. Not sure what the deal was with that, but some homes from the 2000s have used magnetic ballasts. But, in commercial applications, magnetic ballasts were phased out by the mid 90s. I believe some companies sold “residential ballasts” which were essentially just magnetic rapid start ballasts.
