[tor-relays] Cheap Servers? There MUST be a catch

Worried about dominance of OVH for relays and exits? How about Google! Setting up a fast server is SO cheap on their https://cloud.google.com/ platform, it is tempting to set up relays, if not exits there. Looking at their T&Cs they do not seem to mention TOR or banning running a proxy, but a generic list of don't do bad things. I have two ubuntu servers doing running other programmes on there now, and so far cost me $0.78 with fixed IP4 addresses. I have not worked out how to attach IPv6 yet.

Of course set DNS of the machines not to be Google's

So tell me why this is such a bad idea.
