There's a lot of information about the settlement out there. Basically, Ferrari declared that what they had done to increase performance was a "proprietary and confidential" technology used on their road cars. This basically meant that the FIA didn't have the legal grounds to force them to disclose what they'd done. But for some reason, Red Bull seemed to know exactly what was done and asked for several clarifications of the technical regs. So the FIA changed tactics and asked for a voluntary disclosure if the FIA would sign a NDA and not penalize Ferrari. Ferrari were boxed in and knew it, so they opted to make sure no other teams could copy them.

At the same time, the whole plan backfired on Ferrari because it pushed Mercedes to find even more performance to attempt to match Ferrari. Honda and Renault improved as well. Ferrari's advantage was removed as they went down a path that is now closed to them, and they found themselves way behind everyone else.
