No, he's not confused.  Supposedly, using any algorithm other than 3DES
with SSH1 can set you up for some type of stream insertion attack.  I've
never seen it personally, but supposedly the threat does exist.

Furthermore, OpenSSH supports ssh2 and is free, in both the free beer and
the free speech way.  The BSD license is cool like that.
