No, my logic is that no one can compete with an already present oligopoly. Opening that door is fruitless, because it is still impossible for a small business to compete with the oligopoly. ISPs are already very difficult ventures. There is a huge upfront cost, including infrastructure and land rights, that incumbents have already either paid or had paid for by government aid. There has also been huge support from government for incumbents. New ventures are risky, so incumbents are almost always chosen for tax spending. And let's not blow this out of proportion: That door is not huge. It is barely significant in ideal circumstances. Infrastructure quality and price matter more than net neutrality to most consumers.
