hi, i understand that the law does not allow people to use open wifi signals unless they are designated for public use (how should one know? is the computer user required to know enough to check what signal his computer is connected to and do research to figure out if it's open to public access and then seek permission if it is not?). i think the law is wrong. i think the law should say that permission is granted when the signal is left unprotected. my computer could breathe dust from my neighbor's dirt road, it's software, by default, could breathe any open signal. does the fact that the wifi signal would benefit me while the dust would cause me problems make one ok and one not ok?
