Why? Bethesda has a history of making games with best in class modability and the tools they release for moders are fleshed out versions of what they use for designing the game (which usually takes a few months, FO4 tool expected early 2016).

Hell, with scripting extenders and graphics mods, some of their games like Morrowind can become nearly indistinguishable from modern AAA games nearly 13 years later. Bethesda knows this and I can't imagine them locking down anything that could be used to make their games better by their community for decades to come.

More likely that somebody writes FalloutSheep that invades privacy by dumping the inventory of anybody playing on the same network and then users demand Bethesda encrypt the data.
