You may or may not know it, but Wikipedia is not the benevolent information-sharing program it purports to be. There are places out there as the following 2007 article shows, that weaponized Wikipedia in an effort to spread propaganda or, in a very Orwellian sense, ban "thought forms" from existence. https://www.reuters.com/article/us-security-wikipedia-idUSN1642896020070816

The view of Wikipedia being self-correcting is naive since it is the difference between volunteers writing something versus an informational warfare unit equipped with career soldiers writing and making edits. Who do you suppose is going to have more time to contribute to this conflict? Who do you suppose owns the majority of the infrastructure that drives traffic and can, given certain profiles, ban certain IP addresses from being able to arrive at a given website? Who do you suppose is better funded and who, do you suppose, is going to be targeted if they express an unpopular opinion in the Animal Farm the internet has turned itself into?

There are murmurs out there that everything a person looks up on Wikipedia is reported to an "Xkeyscore" like system. All of these things are quite nasty uses of what was supposed to be a knowledge sharing among mostly civilians. Why civilians? Because the government all ready has troves of information. We have to file "Freedom of Information Requests" from them--not the other way around.

The good news is this--one of the founders of Wikipedia--Larry Sanger--is working on a way to solve the problem of Wikipedia. He has started a new project that is called the Encyclosphere.

How does it solve the problem? Well, for ease of communicating what it is trying to do, I will simply say that it is, ideally, a loosely federated aggregator of diverse encyclopedia information that can be distributed in a peer to peer fashion. To write an article on the Encyclosphere, you will, at the moment, require your own domain. The domain will be used via a system of keys similar to PGP to sign your signature to whatever you write with the key in question tied to your domain. This then can be sent off to the above named aggregators. There are other plans to have this information distributed via webtorrent, which would make it peer to peer and not subject to domain tampering.

This allows for a greater chance that a truly decentralized alternative that isn't easily as trackable with software like Xkeyscore can exist in "wiki" format.
