Culver City proudly announces content filtering: Their free Wi-Fi network, according to analysis by the company that was trying to sell a service, had illegal downloads and porno passing across it. Fortunately, Audible Magic stepped in to help poor Culver City protect its most important residents--three movie studios. The press release notes that P2P isn't being blocked. They're only blocking "illegal or pornographic" transmission. Because we know that filters are 100-percent accurate all the time in every case.
Preemptive efforts to cleanse networks results in people employing simple workarounds. A VPN, f'r'instance, would block any ability for the local network to filter traffic. Not that I'm suggesting one go out and then illegally trade copyrighted media or view porn. The latter being a legal activity (depending on content). Rather, Culver City is being fairly proud about snooping on its citizens. And, remember, this isn't about "the kids" or viewing material in inappropriate places that other laws would already cover.
I'm all in favor of legitimate use of copyrighted materials. The trouble is that the balance of power is entirely on the side of those with lobbying power and lawyers who use lawsuits to bludgeon the innocent and the weak.
How soon does Culver City plan to shut down their network entirely in the face of acting as a government-sponsored viewer and censor? Calling EFF, EFF to the front desk, please.
