"Don't use Topaz AI, Anime4k, RealESRGAN, RIFE, etc. Trust me, just don't."
Why? I only know Topaz and I always thought it had its narrow but legitimate uses cases for upscaling and equalizing quality?

Other likely explanations are:
- them not liking how these upscalers look: you can imagine if they can nitpick minor differences between different encodes that most people don't notice, they'll hate the glaring artifacts these filters usually produce
- boycotting AI
The reasons stated against upscaling were that (re-)encoding video files should generally be done in a way that preserves as much of the original information and intent as possible. AI upscalers add information where there is none, thus modifying the video in a way that goes against that goal.
