That's the basic debate, I think.
That anyone who wants to offer an end-to-end crypto solution that doesn't involve customers compiling PGP themselves is
gambling that when the S.49 music stops, they can absolutely convince a judge that although they offered the service
and provided significant assistance in running it (keyservers, perhaps) they genuinely don't have the keys. One position
is that S.12 could be used to frustrate the service in the first place: I think we've concluded that's not realistic. But I think
the protection racket angle, "well, you could run that service, but you'd have to convince a judge that your fancy zero-knowledge
proof was genuine when you claim you can't decrypt stuff on your network, encrypted with your software, using keys that
you store" would be a fairly powerful deterrent to anyone but the most committed.
On the other hand, suppose the CSP in this case were Google, and they lost such an action: they claimed (accurately) that
they couldn't help with a S.49 notice, but the court didn't believe them. What would happen next?
