Or know that they've got limited bandwidth and want to save it for stuff
that is either low-bandwidth or work-related (preferably both).

And no, it *isn't* necessarily cheaper just to buy more bandwidth.

And you don't have plausible deniability. If you have a
carefully-constructed tunnel running over HTTP through a proxy, it's
fairly obvious that you're trying to circumnavigate the firewall. And if
that proxy has suitable logging and analysis (length of connection,
number of connections, amount of traffic), there's a good chance your
tunnel will become obvious.

You aren't invisible.

IT staff can't read the data, but they can tell that the traffic is
there.
