It has never occurred to me before how odd it is for Disney to take public-domain stories, rework them into blockbusters, then lock them up with copyright indefinitely. What a strange combination of ideas.
It's even more striking if you consider that those fairy tales and characters are the products of many, many retellings and adaptations throughout history. The Grimm brothers didn't write them; they just wrote down one version of a lot of them. In a real sense, Disney's modern retellings are just the latest iteration on this process.
You are free to take the same public domain stories, and rework them into blockbusters, as long as you don't copy the changes Disney makes to the stories.
The article was basically bullshit.
