Odds are pretty good that he technically does have access
there... and has never figured out how to use it. Or it is
unreliable. Or it *was* unreliable when he was first told
to use it.

Human problems. Difficult to solve.

I read through their terms of service on the customer end a few
months ago. It's not entirely horrendous, but it's not great,
either. They don't do end-to-end encryption. What they do is

- all access is authenticated with username/password or better
  (several kinds of 2FA are available)

- all access goes through HTTP/SSL (ok, TLS) with reasonable
  algorithm choices

- all files received get dropped into encrypted filesystems
  along with hashes.

- they replicate the filesystems to 3 data centers, probably by
  sending off copies of new files as they come in.

- they log things off-system and sign the logs

Most importantly, they have managed to convince regulatory
authorities that this is sufficient for legal paperwork,
including contracts to authorize sending lots of money various
