Hey Earthlink. I've got a product I'd like to sell you. It's called the "HTTP Blocker" and it will give your users the flexibility to use your service without encountering any of the annoyances of the web. Pop-ups, interstitials, rich media ads - It won't matter. My new product effectively caps off port 80, so that none of these things can get through and annoy your users. Then they'll be able to hang out on IRC, bitching to one another about how commercial interests have ruined the web for everyone.
