Hmm, why would they give away an airplane for free? If we were talking about a FC3 level aircraft with SFM then maybe, but you have to appreciate how much work goes into a full DCS level module. And Razbam for sure isn't a multi million dollar company that can afford to pay their people for months without getting something in return. Sorry, but I don't see the big marketing benefit that would justify such a step.
Now don't get me wrong, I like free stuff as much as the next guy, but I think we have to stay realistic.
