Freenet is promising but it's not even fully done. Experimental stage. I am also skeptic of their more usage of LLM generated code these days.

Freenet (aka Hyphanet) is 25 years old... it's been "stable" for decades. Biggest problem is that content is sort-of hosted locally and considering how much child porn and other criminal content is in its darker corners tha can be risky.

It's also incredibly slow.

Stable and yet never used in live env. It's being rewritten and not at all stable. I don't expect it to become the standard anyway.

I'm old enough to remember when there were more nodes for Freenet than Tor. I don't hink you have much experience with darknets.

Darknet term is mostly used to refer onion services, which have been around since 2004. Freenet was never meant for anonymity, both have separate goals.
