I completely agree with your comment about items listed in editing software are just suggestions. Giving them and you, the benefit of the doubt (since there are always two sides of every story), perhaps the editor wanted you to consider them and get back with them with your thoughts? I know from my own writing and publishing career that editors comments can be frustrating, but that after a more rational look at it, they more often than not seem reasonable. You, yourself has said that no other publication had accepted you in their ranks, could that be because of some of the issues this AI editor pointed out to you? You also mentioned that "the piece was perfect" -- no piece is ever perfect, even Stephen King will tell you that. Every writer -- even famous ones, work with editors and have frank discussions around their suggestions. It's not only part of the process, it is part of how we, as writers, grow.
