OK. Fair enough, but at least some people found it "informative". The technique described probably does affect many networking tools, as you stated, but one should ask if this is a proper coding technique or not (think secure code). The input does not map to the expected output -- and the user should have been told that the port number is out of range. Otherwise, what if he thinks 65571 is a valid port after executing that command? He may be naive, but shouldn't the telnet programmer let him know that he is mistaken in his port choice? As an analogy, it is also true that a C programmer could pull some nice tricks to optimize his code, but that code may confuse another programmer trying to understand it. This is a system, like anything else, and things are based on give/take. I don't see why allowing this to happen actually helps anyone but the telnet programmer -- because it could confuse many users. That's my rant and I'm done -- the users who did not know about this have been informed and that was the point of the original notice.
