Android allows adb install over usb and still sandbox the application. Sandboxing is a feature of the OS and not the store. What's missing from parent description is the publisher signature to retain allowed permissions after upgrades, which still is a feature of the OS and not the store.

Stricter sandboxing makes it more difficult to fingerprint the user and lessens the burden and dependency on legal contracts and policies. Which is what Apple just did by blocking the access to unique device id.

Forgive me, it's wget, a checksum check, and then install command.

This is absurdly false.

This is accurate. HOWEVER being hostile to your OS can result in problems. If google REALLY wanted to do something, they could build in a form of adblocking into the OS layer itself. They can also keep that up to date via app updates from their side. Its definitely a battle, but facebook analytics is well documented by adblock communities and google keeping that list in the OS would be a possibility.

Having said that, google has no intention of waging war against facebook. They have an understanding already.
