Because the spectrum required (UV-C) to do so is harmful to humans and the environment. Putting it EVERYWHERE would cause all kinds of problems.

The article itself mentions solutions to the issue of it being harmful to humans, either by putting it at a distance in the ceiling or just running air ventilation through it, or choosing a specific spectrum that apparently doesn't seem to be harmful due to being blocked by the dead cell layer of one's skin. The environmental issue though also gets talked about, and is suggested to be more the problem.
