What kind of answer do you want him to give you? I don't even understand the point of injecting emotionally charged language like "loyal fanbase". By doing so, you basically turn what could have been a rational discussion into an emotional one. They aren't doing it to spite you, it just makes sense financially.
Plus nothing they are charging for BEFORE the release is actually "dlc", unless you consider the entire game to be DLC. The Cradle maps are retailer-specific preorder incentives, and Babylon is a "feature" of the deluxe edition. Remember, the Deluxe edition is optional, you can opt not to purchase it.
Now, I agree that 0-day DLC is kinda crummy (I wish Babylon was part of the standard edition), but it's got nothing to do with you being loyal or disloyal. They will profit from it, plain and simple, don't take it personally.
