Perfect is enemy of the good. Like you said, the only way to be truly independent if people ran their own infrastructure, and if all the hardware was as 100% FOSS.

Of all the compromises we have to do (relying on Telco providers, equipment manufacurers, etc), using Nearlyfreespeech is the less risky one. They have no history of abusing the trust users have placed on them, and service costs virtually nothing.

The internet isn't even capable of handling 8 billion people each with their own infrastructure. Even if everyone got IPv6 and their own PI address block, most DFZ routers can't handle that many routing table entries. Pooling resources is mandatory for the internet to work. However, there needs to be (and are) plenty of choices of who to pool with, so that you can find a trustworthy one.
