Getting market share is some function of offering better features, offering more features, or something else. Google can lose that starting today, let them die in their own trap.
As the maintainer of Chrome (and to some extent even all browsers based on Blink), Google currently really does have the power to kill web standards, especially those that have a (less efficient) alternative.
This would be true even if the majority of people would be willing to change browsers over an image codec, which they’re almost certainly not.
For their own bandwidth efficiency, they can use AVIF, which is supported in Chromium; about everybody else’s they don’t need to care.
