Great article-- you definitely caught some issues I didn't!
I will be updating my article for 2018, and talking about some similar things as you. I would like to credit your article as a source-- I won't be copying your words directly but in making mine more comprehensive I will necessarily be touching on some of what your article said. Thanks again for reading!
