Just remember that, back in the early days of the app store, somebody made an app called “I am rich”. They listed it for $999, and all it did was display a photo of a gemstone. 7 people bought it.
There’s a saying “a fool and his money are easily parted”, and so long as that holds true, there will be people taking advantage of it. And honestly? I can’t blame them. If you can figure out how to swindle somebody out of $100 for a $10 product, all the power to you.
While dead pixels are annoying, imo stuck pixels (especially on OLED) are far worse. I had an LG CX that had a bunch of dead pixels within the top cm of the display, but I literally never noticed them if I wasn’t looking for them.
Stuck pixels would be a nightmare though in dark scenes.
