Multiple factors, e.g the perceived lack of an immediate need, and also Mozilla's control of the firefox codebase.

For instance, one improvement that a more user-respecting group might contribute is ripping out all the AI slop. But as pointed out in the article, Mozilla like the AI slop and wouldn't accept those changes.

If Mozilla was to disappear, orgs like those I mentioned would likely see a more urgent need to take over in order to break the chrom(ium) monoculture.
