Which is both specious and obnoxious.

Given a choice between a provider which does this and one who does not, I will always choose the one that does not. Unfortunately, there is no PON vendor in my area, so I live with com cast business (on a dynamic IP because I refuse to pay their absurd mark-up on IP addresses). Given a PON vendor in my neighborhood, I'd drop Comcast in a heartbeat.

This is true. However, I'd be willing to pay some amount to cover this difference. Interestingly, Comcast is the only provider where I've been unable to get a static address on a residential plan at any price. They're also the only provider that has tried to charge more for a static on business service.
