Sony would definitely benefit from this.
Square would get a nice bag for it from Sony, too. I'm not so sure that I would know enough about Xbox sales numbers in the past to understand if this would turn out net negative for Square in the long run.
That said, the consumers that do want to own and play FF games on other consoles would obviously be missing out. I've transitioned to valuing my Xbox library above all else under the perception that Microsoft will likely support that library through future hardware iterations. As someone who has converted to all-digital with this new generation >and< someone who has not historically kept old hardware, that's a big value perception for me. I would certainly hope by the close of this generation, Sony indicates some sort of long-term library support too -- not necessarily in the form of additional back compatibility with PS1-3 (though that would be very nice) but just at least saying "sure, PS4 and beyond will just exist as a supported library going forward from now on." In that scenario, they still lag behind Xbox on efforts like FPS Boost and resolution enhancements, though, which for the moment and on pure speculation maintains the Xbox advantage for me. This is all a bit tangential to the actual conversation at hand, I'm just saying it would be a shame for FF to be a "temporary" part of my catalogue, assuming no change from Sony in game preservation philosophy, aside from keeping my PS5 going forward, which gets cumbersome for me since I don't own a home and have floated my entire adult life from small apartment to apartment -- at least my library is all digital though so I don't have to carry a physical collection forward.
