This looks like influence to me... To date, we haven’t actively sought partnerships along these lines. Kaitlyn and Mike suggested it...

I would think that GiveWell talks with his donors and takes idea that it considers good on board. I don't see a problem with doing things that other people suggest.

For example, if GiveWell determined that the Open Philanthropy Project were a waste of resources, do you think they would simply say, "Well Mr. Krieger, you shouldn't give us that money after all."

Do you object in principle to the idea of taking project specific outside funding?

That like saying a researcher who applies to some grant is biased because he has to please the person who give out the grant.
