In a world where all content is housed at repositories controlled by the content providers, as soon as someone decides that such content needs "editing" for artistic, financial or political reasons.. then there's NO recourse, or even a source of proof that the previous version ever "existed" at all. Sounds like 1984 really just arrived.
So who DID shoot first, Han or Greedo? I SWEAR I remembered it otherwise.. but nope, I guess not.
