After watching the video, what jumps to me first is the strange oversight (I assume) of only speaking about Ortega and not mentioning Josef Jelinek, which was another developer of this method, even more because the messages you quote seem to actually be from him (Josef) and not from Victor as you seem to be implying in the video, which was confusing. I think Josef is probably the main reason this method is so popular in the first place. People back then didn't really care about naming methods or who developed what first, they just wanted to get things solved.
It would have been interesting if you could have gotten in contact with Victor and get his thoughts as well to support some of the statements you make in the video regarding the authors.
If for nothing more, it's nice that you made this video to raise awareness for Jeff's work and to let people know that this method was already known in the 1980s and there was some published material on it. I have not read the book, but regardless, the method name branding is a minor issue.
Even though I can absolutely agree credit should be given to Jeff for developing it as a 3x3 method before anyone else (which unfortunately can't ever be proven for sure), by either giving his name to the method or have the reference as method author, I also think it's not entirely fair to disregard the work Victor/Josef had in popularizing it, particularly the 2x2 aspect of it, and completely discard that reference: you mention in the video Jeff did "all the work", and that Victor/Josef "basically just made it popular" as if to say that that has no work involved. I am not sure if that's what you meant, but if it was, it's a bit unfair. It's not the same type of work, but it's also not nothing. Would it be a known and much used method otherwise? Who knows...
I think the sanest route if you want to change it, could be to start using both naming references, so that people can start acknowledging the name of the author and also know what others are talking about when they are speaking about the Ortega method, but it should not be a big issue.
