Dropbox quietly replaces the insides of JPGs with a better compression system (lossless change) to save their storage costs, and then returns it to normal when the file is read. (It may be they do a JPEG XL transform, for all I can remember about the article which explained it).

I wouldn't be too surprised if every big CDN already does something like that internally as a competitive advantage, and if so then the incentives switch around and there's no benefit publically switching to JPEG XL - when everyone has it, there's no easy way to do better than everyone else.

Aren't the biggest costs from bandwidth, not storage? I'm sure they would love to reduce data transmission by 20% for browsers that support it.

CDNs would love to bill customers 20% less for bandwidth used? Customers will be able to move to storing JPEG XL files on CDNs and reduce their own storage and bandwidth costs, but I was responding to the claim that it would be in CDN's interest to hurry the transition, and I think it will be a loss for CDNs.
