Then what's the point? I can make modified bot browser that commits ad fraud as long as I don't use a rooted Android phone?
I don't believe they're being honest with how this will be used. We need to legally regulate remote attestation.

It speaks for itself. Horrid.
In the past the main adversarial pressure has been exploiting security vulnerabilities ("jailbreaking"), but the software industry is getting its act together re that.
