Why does DLSS seem to be so hated?

OTHER THAN the argument of "DLSS shouldn't be an easy way out of giving real world performance uplifts between generations" that's obvious. And I agree.

Also, for most of us, are we really even able to notice a difference in the heat of battle? Or in the blistering turns of a super GT race? I'm extremely picky with my monitors and displays, having gone through TWELVE until I found the right one for my desktop. Despite this, even I haven't really been able to (or felt the need to) pick out wrong pixels on the screen when I'm having fun with the game.

Edit: If you still hate DLSS and still argue against it. Do you think it's the game developer's fault for releasing broken and unoptimized games? Or Nvidia's fault for not keeping up (raw power) with lazy devs? (Think: 'ARK Survival Evolved' or early 'cyberpunk' level of unoptimized)
