We do not consider stories invalid for purely narrative reasons, ever. Doctor Who has been around for a long time, and there will always be narrative inconsistencies. What makes this one invalid is the real world intent. It wasn't intended to fit in with the universe of the TV movie, as our sources say. It was intended to be a totally separate continuity from the one that we -- and everyone else -- consider valid.

And again, read this quote from Nev Fountain:
 * "I think [the darker Doctor idea] can be a dead-end, but you can do a lot of things with the Doctor, especially with an online or radio format — and if you want to accept it as canon, you can. or not. Whatever you prefer."

When those who were behind a story are saying "maybe it's part of the DWU; maybe it's not", that's a good clue that the story in question does not pass Rule 4.
