Water under the bridge at this point.
I mean ultimately you can't really be that mad. FF7/FF8/FF9 just wouldn't have been possible on the N64 in the way Square wanted to make them, Nintendo should've at least offered Square a CD-ROM drive for N64 (64DD went nowhere anyway).
As for them wanting the PS to win, it's kind of like getting mad at an athlete for wanting to beat his old team on his new team. Should've kept the player happy if you didn't want that.
