This is an interesting problem. On a broadcast channel, when a local station attempts to replace the ads the network has put in their shows, with their own ads, the network has some leverage to shut down that process. But on the Internet there are a bunch of web sites and they don't have any leverage at all. They could do an IP filter, which is to say put up a page "This site unavailable on this ISP's network" when a request came in from a CMA communications IP block. That would cause a support headache for CMA with all their customers calling into complain. The other defense would be to create a web page that doesn't cache (it pulls the actual page content through AJAX calls gets around any local script injection). Lastly there seems to be "product" here where you bundle up an EC2 instance and some friendly software on the PC that spins up a VPN tunnel for all of your traffic.

They could use TLS...
