I agree.

It's silly that the wifi owner has to opt-out of wifi sense. Because it's not like it's already difficult enough for a non-techie to securely configure his access point, no, let's add another thing he has to care/know about.

And the way to opt-out is even sillier: you have to append _optout to your SSID. The SSID should not be used to control the clients behaviour imho.
