Right, except in this case it seems wrong. Here is what they are saying in essence. "Here's how we'll work together, you guys come up with these great ideas and we'll execute and become even more wealthy then previously seemed possible. Thanks!" What a great arrangement. Certainly, execution is very important. It's similar to what Thomas Edison said, genius is 1% inspiration and 99% perspiration.
But my reply would be What? If they think they are so smart, why don't they just execute and come up with their own ideas?
They're making millions and millions of dollars because they had a new tilt on an old idea - search. Now, they want to cash in on someone else's genius? They should do their own work.
