So let's say I'm F-Droid, an organization making a direct competitor to the Google Play Store and openly pointing out how much scammy shit is available in that store. My options are 1) submit my identity to Google (my competitor) so they can identify me and choose to revoke that verification at any point, or 2) I can tell all my users that they must go through these scary dialogs AND wait 1 day before they can use my competing product? That's cool, glad we've got the options laid out in front of us.

I forgot 3) instruct my users how to use ADB from another computer to install my competing app. Awesome.

It's really ridiculous.

You'd think regulators should make Google ship a 'Choose my store(s)' screen at setup, but Google thinks the opposite is the case and Google should also be able to control app distribution outside of the Playstore.
