I am skeptical that this change meets the Open Source definition. I can understand that they want to experiment with something new, but the OSD includes a non discrimination clause, you cannot restrict or grant different rights in an open source license to different groups. What they should do instead is dual license, with a license that a acheives their goals for the general populace, plus special licenses for specifc groups that allow them to do things the open source license doesnt. I'm not a fan of CLAs like that, but they are requiring a CLA anyway.
