I understand how this works in terms of mockups and how useful it can be - where it gets confusing is in tools like Origami which uses Facebook frameworks:

>Origami can now export code for the parts of your prototypes you used to have to tediously spec to engineers. Now with the click of a button, you can deliver your animation specs as code to your engineers that they can copy-and-paste into the project.

> This uses our _free, open source_ animation frameworks to deliver the exact same feel across all platforms. Take a look at some sample code this can generate and learn more about it.

Which runs in direct contrast with the above License:

> The Facebook Design Resources may not be embedded in any software programs or other products without express written permission.

Unless Origami isn't considered a "Facebook Design Resource" (and is a different type of resource, correct me if I'm wrong here), this seems like lawsuit bait.
