Even the newspaper industry initially opposed the bill. Ed Otte, executive director of the Colorado Press Association, said one-fourth of the state's newspapers sell subscriptions via phone. The papers worried that the bill would have prevented them from calling new residents, who are legion. This was a battle between little people and big money. Consider the salaries of those in industries opposing the bill.
Telemarketing is big.
It employs about 75,000 people in Colorado. Rutt Bridges is president of the Bighorn Center for Public Policy, which proposed the bill and vows to keep trying. Basically, the people they would not be calling are people who do not want to be called. I don't see how that could harm business. Industrial predators don't want a state law with teeth.
