You made a decision to turn him down. He made a decision to turn you down. That part of it is not really at issue, in my opinion.
You turned him down, he decided to do it on his own, and called it a different name. I don't think I would confuse the two. If he'd wanted to cash in on your TM (as said in the other thread) he wouldda called it simply "Who's Near". Changing the web address to wnmlive was a huge compromise in my opinion.
I think the real sentiment needed is not "learn to code", but more "learn what coding is, how it might benefit you and also just what it entails".
I also can't help but think baby-steps are required. There are so many people who don't even think about how software is created - learning to code is about three layers away from where they are at to begin with. Simply learning the basics of how software comes to be and a basic underlying structure of a computer would be a good starting point.
Anyone can learn how to write a few lines of a computer programming language. Understanding more of the basic principles of software development and computer architecture would be much more beneficial. That is my personal opinion.
