This is why the "guest login" feature on most Wi-Fi routers exists, to prevent untrusted persons (and by untrusted I mean anyone other than yourself and possibly-but-not-always your immediate family) from having access to your entire LAN when all they need is Internet access. Of course it works best when your guest login feature supports time-limited random passwords. Set up properly, guest accounts can make this Wi-Fi Sense bug a non-issue for your own network. That said, I think Microsoft made a serious blunder here; it's inherently flawed and I can't immediately think of a way for them to fix it without getting rid of its entire raison d'être.
