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).
