I doubt there were any direct orders.

The smart way to do this is to find people who already agree with you anyway and then just 'support' them to write the things they would write anyway, just more and to a wider audience. You won't need to explicitly tell them to do anything, so there won't be any orders for anyone to find later. The recipients of your largesse will be grateful for your funding, rather than consider themselves sellouts or employees. And if ever you don't agree anymore, you can just pull the funding again.
