Generally when this is done _well_, you'll end up with multiple ISPs who'll compete on price, so they're essentially selling a commodity product with generally fairly low margins. For instance, a somewhat similar scheme in Ireland (NBI, a state-funded thing which builds FTTH in rural areas where it would not be economical for the other FTTH infra owners to build) has _56_ ISPs currently providing service on its infra (though some of these are regional). Like, this isn't an exciting new idea; similar things have been widely used all over the world for rural broadband for years. The US is maybe a bit unusual in that the local monopolies were in some cases never really broken, so this is going maybe a bit less rural than would be typical. In many countries the local monopolies (Charter and Verizon, from the article) would be required to allow other ISPs to use their infra at a controlled price.
