WEI is like requiring people to get their brain scanned before you let them visit your house. "Sorry, I require a valid attestation from Google that you are a real human," you say. Your friend now needs to drive down to the local Google® Privacy Invasion Center™ and have all of their personal secrets exposed so Google can prove they are, in fact, not a robot. Except, oh no, Google found Linux in their brain scan! The horror! How dare they value their own freedom! Anyone who opposes spying from Chrome and/or Google Play Services is obviously a bot. Nothing to hide, nothing to fear, right? Your visitor, who is clearly not a bot, fails to obtain a valid attestation from Google. You deny them entry to your house.
You have lost an acquaintance.
