I2P is king here but it has a limitation that makes it stronger but less practical. I2P doesn’t generally do outproxies. A few exist but they typically aren’t trusted or used. Instead, I2P tries to keep private by only routing around traffic the originated within its own network rather than piping things from clearnet from one place to another. An issue with arrives that do that is you can see traffic from a honey pot going into a black box and with enough monitoring where it ends up leaving that black box. It’s very difficult to track traffic flow within the network but once it jumps back into clear net you can find it again.

Now while you can argue that it doesn’t come out on clearnet, just originates from there, I counter that with Microsoft Windows telemetry, it might as well be clearnet. Windows is the dominant player at the moment so it’s most likely the traffic ends up on a windows machine. There are really benefits behind the telemetry date but they also means there’s a single point an authoritarian regime can apply pressure to to monitor whatever they want. With advances in AI, chewing through tons of collected data is much easier to do, so the idea of “they can’t stop all of us” is ridiculous. They will just pick off the undesirables in smaller chunks.

Ultimately nothing is completely safe but if you really value privacy, make yourself such an enormous pain in the ass that monitoring you becomes a chore.
