I think it's not the phone company's business that some subscribers pay for such service. I don't want it but it's a big business and provides a lot of jobs. The difference is, the phone customer is *purchasing* the service and not being solicited without permission.
So if the porn industry made 50 billion in telemarketing in your state, would you support it? Not to mention that telemarketing is not being banned.
I don't support *any* unsolicited telemarketing especially in the case of where I'm paying money to avoid it.
