I see this as not much different than those bus shelters that are paid for by JCDeaux in exchange for putting ads there.

Shelters should be free, and so should water fountains. But free doesn't mean nice. I've seen some poorly maintained bus shelters and water fountains.

If people want to slap ads on the side, and increase the quality, then that's great. If your VC funding, or ad funding can pay for a filter on a water fountain, even better.
