The annual competitions are possibly the most overlooked item in Dunkelzahn's Will. They stand out as the only one with no time and no money limits: The foundation is to give any quantity of "additional resources for development".
Most people boast about Dunkelzahn changing the megacorporate scene by triggering Fuchi Industrial Electronics collapse (which he's supposed to have done by giving Richard Villiers just enough additional stock to make him realize he would never control Fuchi and should leave).
Those competitions target the very basis of megacorporate power. Megacorporations have more employees, more facilities, more money and more power. There's no more room for growth. What matters is innovation. Most of Shadowrun is about abducting scientists, stealing research results and blowing up labs. Because megacorporations had no other way to ensure the next breakthrough will come from their own R&D divisions. To remain in the top spots for several decades like the AAA do, they had to either take over or crush any start-up business who could threaten their market shares with a new product. That's what shadowrunners are for, and that's why they required the governement to restrict the extraterritorial privilege (and the security measures it allows to take) only the the largest corporations, to be decided by the Corporate Court.
Dunkelzahn's Will allows the Foundation to grant unlimited funds to such start-up, for additional research, production, distribution, marketing and, most important, security. It doesn't even have to disclose the sums engaged.
