xrichx saidIf you're questioning the morality of the situation, then why not just knock on your neighbor's door and ask?
I make my wifi free and available to everyone. Of course, they don't know I'm also collecting their private information.
Actually, making wifi access available to others may be a crime, because you are letting others use the service providers services without their permission....it's a kin to running a cable over to your neighbor's house and letting them tap into your cable service. That's illegal.
"The Access Point Felony
Even putting up an unencrypted, unprotected wireless access point might conceivably get you in trouble. Let's say that it's a nice day out, and you want to sit in Riverside park on the Upper West Side and enjoy the day. So you plug your Linksys 802.11(g) access point into your cable modem, and sit outside.
You're busted! You see, when you "broadcast" the cable connection, you are opening it up for anyone to potentially use it. So other people can potentially get Internet access from Comcast without paying for it. In Maryland, for example, it is illegal to use an "unlawful telecommunication device" which is a "device, technology, [or] product . . used to provide the unauthorized . . . transmission of . . access to, or acquisition of a telecommunication service provided by a telecommunication service provider." Delaware, Florida, Illinois, Michigan, Virginia and Wyoming all have laws on the books that may do the same thing.
These laws generally treat "sharing" of Internet connections the same way it would treat "sharing" of Cable TV or Satellite TV services. Thus, while you could invite your neighbors in to watch the latest episode of The Sopranos, you probably couldn't hook a coax into apartment 3B so they could watch from home -- at least without getting the permission of the cable TV company.
You can see this in, for example, Verizon's personal DSL agreement, which states that "[y]ou may not resell the DSL Service, use it for high-volume purposes, or engage in similar activities that constitute resale (commercial or non-commercial), as determined solely by Verizon." So, if Verizon determines that your 802.11 connection constitutes a non-commercial resale (and is unauthorized) not only can it cut you off, but it can make you a felon."http://www.securityfocus.com/columnists/237
