openssh source may be free but some of the libraries that it requires are
GPLd. This causes problems for including the ssh code on routers etc.

If I am mistaken, please email me privately, I would be glad to learn more
about this.

I think you're confused, ssh1 is still a very valid protocol. It is well
tested and proven, and in many cases better implemented then ssh2
(though
of course that may change eventually). Don't confuse the desire to make
money with insecurity.

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.
