That's... not what happened? See the timeline I posted here: https://news.ycombinator.com/item?id=49445897

JPEG XL is largely a Google effort including in creating the specification, the reference implementation and later a safer Rust implementation. Why would Google executives want to stop it? From what I gather it's Chrome engineers that didn't want it because it was huge, had little adoption (at the time), and was rather redundant with AVIF and WebP (for Web purposes). Not saying they didn't have related mandates from executives but they also have a lot of say in what goes in and what doesn't.
