AFAIK this is just speculation. Some apps are currently being given away for free when they are usually sold at a price. Their has been no announcement from Apple of the companies so it's been speculated they are free in celebration of the App Store's 5th anniversary. If Apple was involved in this they would most likely feature it on the store. As of now that hasn't happened so I doubt Apple is involved. Edit: If Apple was involved they would probably make some of their own apps free.
