> First of all, I think that ads in the Internet are important, it's a driving force. Without ads there will be no Internet with lots of "free" resources, everything valuable will be paywalled which is a problem for poor people and nuisance for the rest.

Wikipedia might just be the most valuable information resource there is with the Stackexchange network also ranking highly. The former has no ads and the latter has a negligible number. High-quality traditional media are often already pay-walled.
