JPEG-XL isn't an issue of license fees. It's an issue of GOOG/Alphabet being an arsehole. Tabernak, for reals. ;)
@rl_dane JPEG-XL is indeed open, and developped by Google.
they asshole their own project?
@rl_dane @s1r83r
It's not a Google project, it's JPEG — Joint Photographic Experts Group, the same group that's behind original JPEG and JPEG2000, it's a further development of the latter. AFAIK Google only contributed one of the algorithms used — they aren't the sole developer, nor they have complete control over it, like they have over WebP.
@rl_dane @s1r83r
It's a truly open codec having multiple implementations, unlike WebP — in case with which there is only reference one: libwebp, which most software depends on and over which Google has complete control.
That is probably why they torpedo it and push for WebP instead — AFAIK they did drop support for it in Chrome, not sure if they ever added it back.
