I'm not explaining anything to the users, I'm just explaining to you how you're wrong when you state that they "broke the web for their users".

The users are completely irrelevant, because no matter how much they bitch and moan, they're not going to leave Facebook. Its network effects are too powerful. And so, for once, I actually support Facebook. They're using their dominant market position to push a new standard that is quite good. This will hopefully force companies like Adobe to start adding support for WebP by default. Then we'll finally able to ditch obsolete standards like JPEG and its ilk once and for all.
