Well, I think the more mods, TCs, or games in general there are, the bigger is the interst in the 'topic' (like Star Wars).
Which is a good thing, even for the companies.
If they create a good game, they will perhaps even sell more copies than without the community.
Nobody says: "I got the StarWars mod, so I won't buy StarWars games anymore..."

I think having mods based on your movie/game is a proof for a good fanbase.
