- Network operators: it's our network, we do as we please. We have to defend our own services.
- Internet service providers: it's not us, it's the customer who is using the service. Moreover, he/she already pays for it (ie the broadband bill).
Now for munifiber:
- Opponents (normally cablecos and telcos): cities have no expertise and should leave the market to commercial enterprises.
- Proponents (usually cities themselves, but Minneapolis is an exception): competition is insufficient, especially in rural areas. Broadband is a civil right, like roads and water pipes. Besides, munibroadband will spur economic growth and will socially benefit the population. Also, government institutions can use the network.
The matter is somewhat complicated by the 'stupid network' view: operators should acknowledge this inescapable view, cheer cities' initiatives to pay for the upgrade and restrict themselves to the role of service providers. But that would take a major turn.
