I understand your point, but my answer would be: that is not fandom. That is corporations trying to monetize fandom, as they have been at least since the first Doctor Who and Star Trek merchandise hit the shelves.

Meanwhile, fandom will go on merrily doing its own thing, including writing tons of Inspector Spacetime fic, which may or may not relate to the web series, but from which NBC will not profit.

Fandom isn't uncomplicit in big media, certainly, but I also think we're a lot less co-opted and compliant than big media would like.
