In my comment I didn't actually refer to the editing of documents, it was more a meta comment on the definition of history. > They are altering existing works written by people who are long dead, without making it clear to the reader/viewer what has been changed. Have you heard of this thing called "the bible"? It's been regularly altered for almost 2000 years without making it clear to the reader/viewer how and why. Yes, that's a hyperbolic point but it's to show that editing of past works is not new. Writings, paintings, stories, etc... have long been edited and referred to as the original.
