However, it is a pity that it's restricted to condos and large apartment complexes right now. It would be great if services like this were ubiquitous
One obvious solution is to relax zoning rules in Seattle; a lot more condos and apartment complexes would be built if it were legal to do so, and the benefits would extend far beyond fiber connections (see, for example, Matt Yglesias's The Rent Is Too Damn High or Edward Glaeser's The Triumph of the City for more).
