Why are monopolies a problem? Because they stifle competition? Why is this? Because they control a market or ecosystem to the point where they can very very effectively prevent new players from entering it. If we have an ecosystem that a large number of our citizens are affected by and it is very hard for a new company to compete with a few established players, then there's a risk of many of those citizens getting "the short end" because the companies controlling the ecosystem have no incentive to competitively price anything. I think that's as good a reason as any to consider busting a monopoly.
