I really cant comprehend how youre a proponent of open wi-fi. It sounds like you have a vendetta against the wireless companies, but it would have a much larger impact on wireline. Especially in high density areas where you work. Internet, VoIP, IPTV (legal or illegal versions) , all flowing over a free network puts you on unemployment. As previously stated, even with open wi-fi, everyone will still have a cell phone, fixed residences and businesses in range of free wi-fi will not have any reason to subscribe to wired services.
I agree with you that the future is bleak, but endorsing technology that speeds the process of personal hardship isnt very logical IMO.
The Internet would have to come from somewhere. I am not talking about everyone disconnecting their home service in favor of Google's ( or whoever's) free Internet. Much of the Wifi could be from people's home and business routers. Like Cable vision/Time Warner/etc. it would be available to people who are already subscribers; it is a supplemental extension of their home service. It wouldn't decrease wirleline profits and could potentially increase them as people switch to carriers with the most dense Wifi coverage. Google/NYC/other free WiFis would simply add to that density.
