If the government is so keen to ensure everyone has access to at least basic broadband, and it's not going to happen through private investment then we're going to end up paying for it somehow, whether it's through normal taxation, an additional levy or higher service costs subsidising investment.
The stupid thing is everyone's describing this as an internet tax, but it's a levy on fixed land lines. So my gran ends up paying the levy even though she doesn't use the internet, yet I can go out and sign up for a broadband only service from VM and not have to pay it.
