Perhaps true from his… perspective. I’ve found JXL surprisingly awesome and easy to use (size, quality, speed, intuitive encoding options with lossless, supported in XnView & XnConvert for easy batches). AVIF was terrible in real-world use last I tried (and blurs fine details).

I’m still a big Mozilla & Firefox fan, but a few decisions over past few years seem like they’re being dictated or vetoed by a few lofty individuals (while ignoring popular user requests). Sad.
