There are already two free relays on Tor: 
ws://bitcoinr6de5lkvx4tpwdmzrdfdpla5sya2afwpcabjup2xpi5dulbad.onion
ws://oxtrdevav64z64yb7x6rjg4ntzqjhedm5b5zjqulugknhzr46ny2qbad.onion
The missing link was, at least for us noStrudel users, the client. Now we are able to have a fully private Tor experience - client + relays.
