In both cases, where buildings had exclusivity agreements or had the fiber providers lay the fiber themselves, residents are worse off.
This is an opportunity for wireless. I've lived in buildings with exclusive internet agreements. I was able to bypass those in some cities back when WiMax was still available. I got double the speed for half the price when I was living in an AT&T building, and the same speed for half the price when I was in a Qwest building.
I'm not a fan of the new breed of satellite internet startups, but if they put fear into the wired/fibered carriers, then at least some good will come out of them.
