TL;DR:<p>> Just add "_nomap" to your network's name to opt out from Google's service.<p>> Microsoft requires you to include "_optout" somewhere in your SSID.<p>> So you'd need to create an ID such as "1234_optout_nomap" to reject both services.<p>––––<p>Ugh, this seems really annoying, because SSIDs are limited to 32 chars, and you give up 13 just opting out of these services
