ISPs say US should force Big Tech firms to pay for broadband construction

This type of logic only makes sense in the case of public utilities, not privately owned companies.

What do they think we're paying for? I don't see how the non-amortized costs (ie, non-infrastructure-buildout costs) could ever approach the amount they pull in revenue. This also ignores the fact that the telcos have gotten somewhere in the double-digit billions of dollars (iirc, around $40B) in taxpayer money to build out fiber infrastructure, that they never delivered on. What are they using this money for? What are they using their subscription revenue for?
