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.
While technically correct, not really feasible on mobile devices, especially when they have not been rooted and they are controlled by the telco you get your service from.
Wdym not feasible? I'm currently doing it on a non rooted android device using Mullvad VPN. Not sure what the telco has to do with ads but you can remove all of that bloatware using adb anyways.
Speaking generally, but if you lack the knowledge how to root a phone, if you're just using the phone as it's given to you by the phone company, they tend to control the things on there to a certain extent, and settings have a way of being switched back to the default values, etc.
Not that it's literally impossible to do.
P.S. and to be honest I'm also over using the work rooted, I really mean to say one where the user has changed portions of the phone away from the default software that the phone company has on it.
