While I agree with the need to create a dispute process for isp bannings (as its inevitable they'd take down innocent users), I don't think you can take the emphasis off unsecured wireless routers either.
You can give a person the best wireless router out there, but if they don't know how to use, how to set up a randomly generated superlong password, and which encrpytion method to use (WPA2-AES?), the best router isn't going to help them.
Perhaps routers should be issues with wireless turned off by default, so the user has to hardwire it in, unless they know what they are doing?
a little bit of googling would help set up a router as well.
