Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      One of the responses I hear when people talk about the privacy-serial-killer that is Android is something like “Google is in the advertising business”. This has never really convinced me.

      They bought an OS with a powerful permission and inter-app communication system. They started with permitting very powerful / useful apps able to work together and be well integrated into the OS and have had to figure out how to increasingly restrict / sandbox them over time.

      Yeah. But it was a lot of time. Apple had already production-tested the idea of asking users for critical permissions and making apps survive a “no”. For years by the time Google belatedly began copying those ideas.

      Google had AppOps since something like Android 4.3. They started on that a long time ago. It only became something they wanted to deploy in the standard user interface in 6.0 but it had existed as an available (but not exposed to non-power-users) feature for a long time already.

      They chose not to prioritize making it one of the prominent user-facing features for a long time but it's not like they didn't know it was a good idea. There's essentially a budget of (potentially) breaking changes that can be made in a release and they prioritized other ones.

      In a world where Google was the only mobile OS developer in the world, or where Google was some scrappy startup, this would make sense. In the real world Apple prioritized these changes and made them all ages earlier. Google just didn’t prioritize privacy.

      At the end of the day, if management says “we’re going to prioritize [long list of features that aren’t privacy, and oh yeah we’re going to build our own *town*” that’s management saying privacy isn’t that important.

      For privacy features, it's not really about resources assigned to it. It's about needing to make breaking changes and only being able to get away with a certain level of that for each major OS version and API version.

      This is mostly a false narrative. For some things (hidepid/sysmon) it's partly true, but zeroing out call/SMS data would never have broken anything. CM/LOS did it with no problems.

      CyanogenMod / LineageOS used the functionality Google wrote. PrivacyGuard is a UI to AppOps, which is the same way Android's own 6.0+ permission toggles work for legacy apps.

      IIRC (might be wrong) the original Privacy Guard was different, introduced before AppOps existed. And Google removed access to AppOps soon after adding it, only brought it back considerably later.

          You're wrong about the history of this. AppOps wasn't removed and has remained accessible to power users the whole time. It was never a viable implementation of the feature for widespread use. It has bad usability which is why it's only used in ignore mode for legacy apps.
