Please do not misinterpret the delegation strategy explained in this post. The Foundation is not trying to artificially create decentralization by delegating to pools that would not survive without delegation. That would be against the principles of how Cardano works and would have little to do with decentralization.
I would even argue that when you think the decentralization aspect through and also consider operational resilience (from a network perspective), you want to have pools that are strong and that are close to the point of saturation, because this is how the system works.
