Webp is a smaller file size than jpeg for the same image quality in almost all circumstances - so it’s more efficient and quicker to load. It also supports lossless compression, transparency, and animation, none of which jpeg do. And the jpeg gets noticable visual artefacts at a much higher quality than webp does.
People didn’t adopt it to annoy you. It’s started to replace jpeg for the same reason jpeg started to replace bmp - it’s a better, more efficient format.
