Would an outgoing ssh request be hard to discriminate from an outgoing openvpn request or an outgoing https request? I don't know enough about how the protocols work to understand.

No. But the point probably is: it is much easier and more economic to block the receiving end once by figuring out what it is than having to scan every single outgoing connection all the time.
