When your games are not selling well the easy and short term band aid is to try to reach more platforms.
That's what Square Enix is trying to do.
But the exclusivity is not the real issue.
Otherwise they'd need to explain why there are games that on PS5 alone have surpassed 10m units while their premium titles are stucked at 3-3.5m.
Their IPs are indeed damaged and have lost importance among younger generations but not because of exclusivity, because of a decade of disappointing releases that have made a lot of public becoming uninterested, this is not something the CEO will tell you publicly.
As you can see the fact they just released FFXVI on PC won't change anything, the title isn't perceived to be particularly good and sales seem to be modest.
Let's not even talk about how laughable would be to lose time on Xbox, a platform with zero fanbase whose platform holder is going full multiplatform.
Switch 2 is a platform they need to consider in Japan, but they'll have to understand how to make
table tops their high end AAA games run on it. Imo for AAA releases they'll focus on PlayStation + PC day one going forward.
