writes "According to Freedom to Tinker, MA, TX, SC, FL, GA, AK, TN, and CO have introduced similar bills that would make it illegal to possess, use, etc. "any communication device to receive ... any communication service without the express consent or express authorization of the communication service provider" or "to conceal ... from any communication service provider ... the existence or place of origin or destination of any communication." (Additional legalese removed for the sake of brevity.) This would seem to outlaw NAT, VPNs, and many other security measures. In other words, don't secure your communications, just sue if you don't like who receives them."
The bills define 'communication service' as just about any sort of telecom service that is provided for a charge or fee. In effect, they would extend the already-extant laws relating to theft of cable TV services to any telecom service. For example, if your ISP charges per computer connected, using a router/NAT device would be illegal if these became law.
