The screenshots/videos of them doing it are pretty wild, and insane they are editing creators' uploads without consent!
To me, this clearly looks like a case of a very high compression ratio with the motion blocks swimming around on screen. They might have some detail enhancement in the loop to try to overcome the blockiness which, in this case, results in the swimming effect.
It's strange to see these claims being taken at face value on a technical forum. It should be a dead giveaway that this is a compression issue because the entire video is obviously highly compressed and lacking detail.
Such as?
This seems like such an easy thing for someone to document with screenshots and tests against the content they uploaded.
So why is the top voted comment an Instagram reel of a non-technical person trying to interpret what's happening? If this is common, please share some examples (that aren't in Instagram reel format from non-technical influencers)
It's difficult for me to read this as anything other than dismissing this person's views as being unworthy of discussing because they are are "non-technical," a characterization you objected to, but if you feel this shouldn't be the top level comment I'd suggest you submit a better one.
Here's a more detailed breakdown I found after about 15m of searching, I imagine there are better sources out there if you or anyone else cares to look harder: https://www.reddit.com/r/youtube/comments/1lllnse/youtube_sh...
To me it's fairly subtle but there's a waxy texture to the second screenshot. This video presents some more examples, some of them have are more textured: https://www.youtube.com/watch?v=86nhP8tvbLY
Perhaps a useful analogy is "breaking userspace." It's important to correctly diagnose a bug breaking userspace to ship a fix. But it's a bug if its a change that breaks userspace workflows, full stop. Whether it met the letter of some specification and is "correct" in that sense doesn't matter.
If you change someone's appearance in your post processing to the point it looks like they've applied a filter, your post processing is functionally a filter. Whether you intended it that way doesn't change that.
No need to downplay it.
ETA: I rewatched the video to the end, and I do see that they pose the question about whether it is targeted at certain content at the very end of the video. I had missed that, and I don't think that's what's happening.
