There is no guarantee that two or more privately owned broadband service providers will enter and remain in Syracuse for the long-run. For example, Time Warner Cable may compete with new competitor Verizon for a period of time, but then agree to sell or swap its local operations with Verizon's in another market (or vice-versa), each gaining a market monopoly.
This has happened between Time Warner Cable and Comcast in Los Angeles, Philadelphia, Dallas-Ft. Worth, Minneapolis-St. Paul, Cleveland-Akron, and surely other places (See: FCC AdelphiaPetitiontoDeny.pdf, pg. 77).
We need publicly owned and community controlled broadband if we are to assure there will be competition—and more to the point, low prices and quality service—in the Syracuse market.
