You've made many predictions about what "competitors" will do. Why the hell haven't they done them already? Data service in this country is terrible, for most business and nearly all residential customers.
Competition will drive down prices, increase speed and result in the best possible customer service!
Except that in markets with expensive outlays to get started that rarely happens because the expenses put a natural limiter on the amount of people that can actually mount competition making that number low enough that the competitors can essentially carve up the market, price fix and then all suck approximately equally, indefinitely. Just like ISPs and cell phone carriers do now (and will continue to do so until the government steps in and forces them to fix their shit).
In regulated markets. After all, things like anti-cartel laws are regulations, and we absolutely do need those.
