You wanted to make the argument that this is a morality question, with you defining the terms and what is moral. That is simply not how the world works. If you want to provide information that your customers can freely use, there are consequences. One of those consequences is that others may use that information in ways that you do not approve. Therein lies your choice. I think the correct choice was made. The only anomaly is your complaining about the consequences. I might not use that information in a commercial context but that is solely my choice. If others decide to do so, they are on solid legal ground and there is not a damn thing you can do about it, regardless the logical absurdities and legal distortions you attempt.
As for your quote from Oxford: Again, we are not discussing an "idea", which in any case not protected under copyright, but a fact, also not protected. "Ideas" may be patented, not copyrighted. You repeatedly state that you have examples, case law, etc., but never cite any except one inapplicable Wikipedia article, the Betamax decision. When the United States Copyright Office says, "Copyright does not protect facts, ideas, systems, or methods of operation, although it may protect the way these things are expressed.", why do you think they are wrong?

BTW, we had a lot of old sayings in the Navy about Marines, but that is as irrelevant to the discussion as your citation. My home range is 103 at Camp Pendleton and I've shot with many fine Marines at Camp Pendleton ranges 103 and 117, Twentynine Palms and Quantico. USMC is an outstanding institution for many reasons, but it is just not relevant here.
Not getting baited back in to this. I said my peace, this isn't a legal forum. I did find a number of ways this could be protected, legally. All of which are an off topic discussion, and all of which go against the very reason I am here. All of which would only hurt the end user. I am here to support shooters. So as not to get dragged back down the rabbit hole, I am moving on. In a productive way, that supports those who are looking for help.
