This makes sense up to a certain point, but even though I'm not a huge fan of Epic games (I like them, just not always my thing), they've really gone up in my esteem with what they are doing with the Unreal Dev Kit, which is the exact opposite of what iD is doing.

Their monthly updates to it are always full of interesting new features, and it really allows anyone to get into to it and make cool shit.
With crytech seeming to be planning on releasing a similar version of sandbox to the public, I'm surprised and saddened I won't be able to do the same with iD tech 5.
