No, Moving Your SSH Port Isn’t Security by Obscurity

Security provisions have a "mechanism" and a "key."
The "mechanism" is public knowledge (ie. how key cards are validated.)
The "key" is private (ie. only specific people have key cards.)
Security by Obscurity means the mechanism is also private.
Changing port numbers is not hiding the "mechanism," since people knowing that you changed the port does not compromise it (they still have to port scan to find it.)
Also port scanning can itself show up on intrusion detectors.
