The fact that you have to change your SSID to opt out of third parties using it is... shady at best. What happens when two competing third parties have conflicting name requirements for you to opt-out?

Knowing Google it will still go somewhere.

No worries! One or the other of them will change its mind as soon as any significant number of people start using the option.
