Imaginary stories are serious business. No stories have been "undone". They still exist on paper where they were left off. The difference is they aren't being added onto.
Pretty sure most of these criticisms were answered before. Many of them are creative choices that you either buy into or not. Why is Hippolyta blonde? Because they felt like it. They aren't literally creating a new reality down to the atom. It's all for entertainment. If you're looking for reasons behind everything, you're missing the point of comics.
