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?
