There’s some politics involved. Basically, everyone is rallying behind JPEGXL instead of WebP, but Google refuses to support JPEGXL in Chrome. The reasoning they gave is weak, so it’s assumed that they’re just trying to force the format they invented on everyone because they can.
IIRC, performance of the two formats is similar.
Fuck yeah.
For anyone out of the loop, look into Freetube and Grayjay. There are other apps that do the same thing too, but those are good to start with.
