That's not what I understood from the article you linked. It sounds like the issue mainly stems from uncertainty on whether Square Enix would be able to push a patch out and have it reach all of their player's across platforms at the same time. But Yoshida never points fingers on which of the three is to blame (my guess is Nintendo, they're online infrastructure has never been great). "One of the issues Yoshida noted, however, was that many companies don't consider how updates to the way online services are operated and regulated can impact an MMORPG. "Those can become a hurdle when we consider operating FFXIV for an extended period of time," he said. "So when I talk to those first-party companies, I ask them, 'Do you have the capability to prepare for that, do you have the resolve that you're going to make sure to take responsibility and take care of those, do you have that willingness?' "If we are able to come to some sort of agreement, a handshake so to speak, or if it does end up being that unfortunately we can't do a handshake with Final Fantasy XIV, either way we'll make sure to communicate with our players. But we have been tenacious--we've been trying to keep at it and be persistent about our conversations."" Considering that cross-play between Microsoft, Nintendo, and PC is supported for multiple games now (Rocket League, Minecraft, and Fortnite), I think it's safe to say that Sony's the one holding back cross-play as a whole. As in to say, even if the above issues were fixed, I wouldn't be surprised if Sony said no anyway.
