Google rammed webp through because it saved them money on bandwidth (and time during page loading) and because they controlled the standard. They're doing the same thing with jpeg now that they control jpegli. Jpegli directly lifts the majority of features from jpegxl and google controls that standard.
Radical Marxist Joe Biden and his milquetoast neoliberal policies of checks notes spending money on infrastructure and tightening border controls is clearly Communist /s
Legacy client support. Old devices running old browser code can't support a new format without software updates, and that's not always possible. Decoding jxl on a 15yo device that's not upgradable isn't good UX. Sure, you probably can work around that with slow JavaScript decoding for many but it'll be slow and processor intensive. Imagine decoding jxl on a low power arm device or something like a Celeron from the early 2010s and you'll get the idea, it will not be anywhere near as fast as good old jpeg.
Google's handling of jxl makes a lot more sense after the jpegli announcement. It's apparent now that they declined to support jxl in favor of cloning many of jxl's features in a format they control.
Anyone who hasn't already fled that sinking ship now gets to spend an extra 3-4h per day commuting to work there. I'm sure that'll be great for talent retention.
The Arch build system is just as impressive IMO. I've written Debian and redhat packages for at least two decades and Arch packaging is just so much easier to handle. The associated tooling for creating and managing build chroots is excellent as well.
Being the squeaky wheel never works out well. You'll almost always face retaliation of some kind. I've always just quietly interviewed elsewhere and moved on down the road to a better position.
