Limiting ADB is the obvious next step. Even if this one specific feature request does not come to pass, Google has cornered everyone into relying on a developer interface for any normal personal computing tasks, whether running on-device or through USB/wireless. It's quite clear at some point in the future you will either be required to surrender your identity to them and pay a yearly fee or be severely limited to continue using it in any meaningful capacity, because Google does not want you to develop applications on Android outside their controlled channels -- and it's a developer bridge, the battle was already lost when they did not back down from the changes forbidding normal, legitimate ̶s̶i̶d̶e̶l̶o̶a̶d̶i̶n̶g̶ installation.

>Don’t even get me started on OEMs that force an audio warning such as “This call is being recorded,” when it’s in places where it’s not legally required.

This is also Google's fault. Their dialer--that OEMs increasingly pick over their own, despite their always being much better, see old MIUI one for example--just blanket applies the rule almost everywhere. Especially annoying on all MediaTek SoCs that do not support the feature on an hardware level at all through proper, reliable third-party applications. As if you didn't need any more proof you don't own "your" devices. But maybe in a couple years Gemini will be able to listen to the calls and summarize them for you, just need to go through the approved surveillance channel.
