The really weird part is that both webp and jxl developments were largely funded by Google so its not Google killing a competitors format over their own but someone in one part of Google killing the format someone elsewhere in Google developed over their pet favorite.

There's no form of cloak-and-dagger BS more vicious than internecine BS.

PNG went through that when Microsoft kept throwing incomplete and buggy support for it in IE. Hopefully something will come along to buck Chrome's monopoly and JPEG-XL will have its chance.
