Re: Everything will be FREE!!
That depends if you're talking about a raw bit-pipe or a "full-service" ISP. If all the ISP is doing is providing a fat pipe, mainly to overseas peering points and local server farms, then there's no point to competing on whether a prettier bill is worth a price premium. If the market is efficient, then everyone will end up paying pretty much the same price as the network provider charges, especially if either advertising rules or network standards rule out competing on how much they're lying about contention ratios.If you can shop around and get a better deal, then either you're exceedingly lucky or the market is inefficient (electricity is a good example of that).
If we're still talking about traditional ISPs with email, miscellaneous mirrors, and other services, then the national network provider should allow retailers to add features, but they should also allow customers to buy access directly at the same price.
