As long as it is not at launch, it will be a PR disaster once the community is established and they try to do what they tried to do with skyrim. They cannot afford to destroy the mod community given that although there is money there, it is a nightmare of legal issues on copyright's alone. On-top of that there is the maturity issue, how they will manage sex mods without locking them out? How will they deal with modders building off of one another... Then there is the lack of sales through piracy given the loss of complicity in mods, it is a mess.
