This idea makes sense, empirically. There is a cost to provide internet, and low-income individuals may be more willing to provide a combination of valuable assets (cash & data), while higher income individuals would be willing to provide more cash in exchange for no data.

Regardless, the end payment is the same, it's just a question about how you want to pay.

Edit: For those who think this may be a money grab, remember that the government is getting tax revenue out of the profits ISPs make from monetizing your data. While the ethics of this are debatable, the alternative is zero additional government revenue. So the ethics of privacy need to be weighed against the ethics of providing programs for communities that could be beneficial.
