If your wifi broadcasting your mac address is a concern for you then turn off your router.
No one has ever claimed wifi was a secure protocol. Google is just recording what people are broadcasting. I can see why people would be upset but it is their own fault, I am sure google isn't the only one trolling neighborhoods for unsecured connections.
Instead of telling people how to protect their info they tell google to stop listening. Their concern shouldn't be google but the people who broadcast their info for anyone to record.
