If it were simpler to run a relay on a provider that allows it, and it doesn’t cost much (say $10 a month) to give Tor users a little more speed, that’d be helpful. The last time I looked at the documentation, it seemed quite involved and complex (of course, I wouldn’t want the security of Tor users to be compromised due to any misconfiguration).
If there were something for Tor like Sandstorm for web apps or Algo for WireGuard, more people could run relays and help everyone.
