Why was that modded troll?

If you look at the amount AT&T, Comcast, Verizon spend on marketing you'll find it comaparable to what they spend on upgrades.

Comcast spends millions on TV commercials to tell you how Comcastic they are.

These companies are government sanctioned monopolies that run humongous bureaucratic hierarchies. They have diminished incentive to be efficient because entry level into the market is so high as to preclude real competition.
