As a technicality you would be correct. Games can be removed from PS+ though and it also lauched day and date on Steam. So calling it F2P instead of a PS+ Day One would be a little harder for fans to swallow on PC where it would still have been $40. See also the aforementioned Halo Infinite which launched on Xbox first then PC but only the multiplayer component is F2P on both. You can play SP with Game Pass Ultimate but you need to purchase a license to do so on Steam.
