> Oh, and free speech and anti-censorship and all that jazz.

That jazz is increasingly played by the same band of 185.220.0.0/16 exit nodes, and plays it in a scale which is all but Anonymian.

No part of hosting or visiting onion services involves exit nodes. Onion service traffic stays within the Tor network instead of exiting to the clearnet.

Run more exit nodes then, and more onion services so they don't need to involve exit nodes.

It's also not such a big deal, provided they aren't messing with your exit traffic which you did encrypt, right? There are few exit nodes, but a great many non-exit nodes which still help anonymize your traffic. If you think it's a problem though, run an exit node.

I’m sure lots of people would run exit nodes if it wasn’t the equivalent of putting a flashing neon sign saying “please ruin my life mr government” in front of your house

I would like to know more, can you give me some insight?

Well if you use Tor somewhat regularly and check your exit node IP, it is about 50% possible that yours is in that subnet each time you renew the route. Which begs questions.

Maybe I'm wrong, but it would look more benign to have exit nodes distributed without this much bias towards that particular subnet.

It's only 185.220.100 [0] and 185.220.101 [1] that contain all those relays. Some of the bigger German families work together as "Stiftung Erneuerbare Freiheit" that's why you see a big cluster there. But Tor never uses relays in the same /16 for a circuit so it's not really an issue.

Correct. "Stiftung Erneuerbare Freiheit" acts as LIR in charge of the address space, handing out chunks of that space to exit relay operating non-profits for free, but does not operate any Tor infrastructure themselves and has no visibility into the traffic. The cost for us are the RIPE membership fees (approx 2000€/yr).
