Two days ago, Comcast did something that would be inconceivable if it was any other company than Comcast: It turned 50,000 residential Xfinity modems into public WiFi hotspots. There are 50,000 paying Xfinity customers in Houston, Texas who are now broadcasting free WiFi that anyone can use. As far as Comcast is concerned, of course, this is a genius move to blanket the country in high-speed WiFi (and there are plans to hijack 8 million more modems by the end of June) -- for Comcast's customers, though, this is egregious monopolistic overreach taken to the next level... and it's possibly illegal as well.
