First, foster competition. I don't know the NY landscape, but in the West Coast, it's not uncommon for a residency to have effectively a single option for ISP. Ensure consumers have options (incentivize creation of new ISPs? Stop allowing big corporations to buy small ones? break up big corporations and force them to compete?)
Second could the government offer public internet? (ie, be a player in the market).
Only as a last resort should these types of heavy hand price enforcements should be taken.
