Is It Fair to Say "No Ads" In Our Commercial-based Society?

Webkinz has ads. Some people don't like it and are trying to get them taken out.

IMHO, ads give the company more resources to have more fun stuff. So long as they aren't intrusive, annoying or discontinuous, why not? The ads are for things the kids know exist anyway (ie. Alvin and the Chipmunks movie).

How much is too much though?
