Indeed so.
The thing is, if they can theoretically set up a warehouse of unattended cable modems, i.e. virtualise the viewers, the next logical step is to virtualise the cable modems as well. And if THAT is possible, and I know it is, it's easy enough to create tens of thousands of virtual "customers" in a cheap backroom setup. Voila - viewer numbers up to improve the stats, and all watching the Tucker C ****-Show or whomever they want to promote this week. There's big, BIG advertising money in those numbers...don't think they wouldn't try something like this.
