While manufacturers like GM, Chrysler/Jeep, Ford, Toyota (go down the list - pick one) don't actually manufacture the filters that have their name on them, I would wager that not only do they have very specific requirements for their manufacture, as well as wanting to keep tabs on those filters, particularly oil filters. If there is ever an engine failure, example a Ford V6, and it's running a Motorcraft filter, then it might be more difficult for Ford to deny any culpability.
Maybe I'm wrong on that, but since my earliest days (1960s) I've always had a preference for 'factory' parts.
