Here's some other creators also talking about it happening in youtube shorts: https://www.reddit.com/r/BeautyGuruChatter/comments/1notyzo/...

If you open the context of the comment, they are specifically talking about the bad, entire-image upscaling that gives the entire picture the oily smeary look. NOT face filters.
EDIT : same thing with the two other links you edited into your comment while I was typing my reply.
Again, I'm not defending YouTube for this. But I also don't think they should be accused of doing something they're not doing. Face filters without consent are a far, far worse offense than bad upscaling.
I would like to urge you to be more cautious, and to actually read what you brandish as proof.
