I don't get that impression from them at all. They maintain a very comprehensive and useful listing[1] of 3rd party licenses which goes over their histories, tradeoffs, and whether they're compatible with the GPL. And that compatibility is treated independently of whether they consider those licenses to be 'Free'. Of course they'd prefer use of their own licenses, but this self-interest takes a back seat to helping the overall ecosystem.
