Well, the Internet existed before web ads were a thing, and it was a better place in many ways. I wouldn't mind losing a lot of the current noise (twitter, facebook...) to end up with a network of public services, subscription-supported businesses, and fan/volunteer-powered resources.
I've always loved the idea of a back-to-basics www2 project. Not enough people care about this stuff for it to ever work though. 99% of people are perfectly happy with the FB/Google/etc world.
