gollark: It's also a several hundred megabyte blob with, if I remember right, *every permission*, running constantly with network access (for push notifications). You can't remove it without reflashing/root access, because it's part of the system image on most devices.
gollark: It is also worse than *that*. The core bits of Android, i.e. Linux, the basic Android frameworks, and a few built-in apps are open source. However, over time Google has moved increasing amounts of functionality into "Google Play Services". Unsurprisingly, this is *not* open source.
gollark: Which also often contain security changes and won't make their way to lots of devices... ever! Fun!
gollark: This is at least slightly better than the situation if you use your manufacturer's official OS images, since you can at least get new *Android* changes without updating the kernel.
gollark: You're basically entirely reliant on your device manufacturer *and* whoever supplies them continuing to exist and being nice to you. I think there are still a bunch of *remotely exploitable* vulnerabilities in the wireless stack present on a bunch of phones because nobody has ever bothered to patch them.
