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’ve tried running Replicant and degoogled Lineage OS on an old Samsung phone many years ago. The experience was a bit rough, but tolerable as long as you’re a tech enthusiast and willing to make some sacrifices. Back then it wasn’t quite acceptable to me, because my bank app didn’t work. Then they announced that they were going to phase out the old code paper, so authentication through a mobile app was seen as the only acceptable method going forward.
