When it comes to censorship in many countries across the world, we're in a pretty sad state. Thankfully, there are a number of tools available from the online community which facilitate free viewing on online content.
With Psiphon, users are given access to proxies hosted across the world. It works as a peer-to-peer system which is powered by the community which has Psiphon installed.
Upon installation of Psiphon, your system will be used to power an online community and your very system will be providing other users with the option to censored online content -- alas you're both a client and a server.
Since the network is decentralized, it is very difficult for censors to be applied to individual IP addresses.
If you're in a country where censorship rules apply, or you'd like to help out the anti-censorship movement, then Psiphon may very well be what you're looking for.
