That is a very odd thing to say in a post that also mentions WebP. I would say that of all the commonly supported lossy image codecs released since 1992, JPEG takes the least advantage of human perception quirks.

webp doesn't preserve quality it actively makes the web and images shittier.

WebP generally preserves higher visual quality at the same compression ratios as JPEG. You can make bad looking images with either codec by demanding smaller file sizes, but all else equal, WebP usually looks better.
