The Chrome team says they’re not going to pursue Web Integrity but…
it is piloting a new Android WebView Media Integrity API that’s “narrowly scoped, and only targets WebViews embedded in apps.”
They say its because the team “heard your feedback.” I’m sure that’s true, and I can wildly speculate that all the current anti-trust attention was a factor too.
I think it’s less, “We’re worried people will flock to Firefox,” and more, “We could get in a lot of legal trouble for trying to force everyone onto Chrome”.
