Ask HN: What OSS projects exist for a distributed internet?

Centralized control over the internet is becoming a bigger and bigger risk for the freedom and autonomy of people all over the globe.

As countries experiment with (and grow more confident using) internet isolation/kill switches, we are losing our right to be able to speak up unconditionally, potentially when it matters the most.

To combat this, I am curious what open source projects exist to create a distributed internet?
