If you haven’t heard of Tor, it is alternative internet - one with privay in mind. I’ve recently started to watch a lot of technical talks online. The two main guys behind Tor are some of the best speakers I’ve seen. They describe in great detail how open source works and the myriad of open source projects around Tor in this talk:
and in an older talk they describe how countries have tried to censor Tor and how they have combatted some censorship (interesting for the technical measures deployed):
Of course as is metioned in the first talk, Tor is mainly funded by the US Government. Asked why they should be trusted - they say they shouldn’t be. Don your tinfoil hat now!
