Here's a harsh truth and a reality some tech users need to wake up to.
Google has never cared about open-source. They have never cared about user-choice/user freedom. They could easily tomorrow make Android closed-source and that would be the end of Android. It has always been about control. Apple got that authoritarian idea correct long ago by locking down the entire OS.
Google is allowing open-source modding only because there's a large community out there that cares and wants it to thrive. And since it runs on Linux, it would make Google look VERY bad if they removed bootloader unlocking, open source, removed features that causes issues for custom roms.
Google doesn't care you YOU. If they really cared, they wouldn't be slowly removing features or adding anti-user features that in the long run, don't benefit anyone but them.
I'm glad the government declared them a convicted monopoly. I'm still ashamed it took them this long to finally go through with it.
What an insane world we live in.
Personally, it's not Google's place to dictate how an app verification ecosystem works. If a company has developed an app, they need to be the ones to make sure it's secure in the first place, not trusting a monopolist tech company that has almost all control with how someone uses their phone.
Google has rules yes, but Android is open-source and should be open with a free & open market for apps. After all, we paid for the device.
