Personally, I think if a company (EA) with a goal of making as much money as possible* has the technology that enables them to squeeze more money out of the players, they will use that technology. And I really doubt that they prohibit their affiliates to use it. It's more likely that they encourage the usage of that technology.
Now the question is whether CG implemented it or not. I think it depends on how can they meet the monetary expectations (or even requirements) of EA. Usually I'm pessimistic about the intents of profit-driven companies, though I'm willing to give the benefit of doubt to CG. The fact is that we'll never know as it's obvious that they never ever admit it if they use that technology.
So these kinds of speculations and discussions make no sense and lead nowhere.
*Edit: I mean if that's their main and only goal, which is clearly shown by the iterations of basically the same games over and over (I'm looking at you Fifa and co.)
