For instance, I'm imagining a wiki-search engine. The builder would need to load the first few hundred thousand results and then add some sort of user moderation system, where search results get a reputation and site submitters get a reputation as well. Donation funded, with maybe one sidebar section for curated ads that are tied to search results and not with a tracking cookie or fingerprinting. With a few tweaks, that would be a really good start, right? Once it reached a certain point, it would be overrun by the same systems, using human and bot armies to bias results towards the results that would make them the most money. As long as there is a profit to be made somewhere, people will undermine any obstacle placed in front of them to make it, and I can't imagine any fix for it that isn't "run your own servers and pay for it out of your own pocket".
