I think the animosity doesn't derive from the PS4 version arriving earlier than the Switch version or from the general support towards the Switch, but rather from the very bad excuse they gave us. Problems with the UE4 arised. An issue with compaitibilty. Ok. Stuff like that happens. But then they shouldn't have anounced it before even testing simple things like that. This is basic level here, and they managed to screw up. You don't expect such nonsense from a juggernaut like SE, do you? Well, neither does him.

Furthermore, Nuvendil seems pissed because he works with UE and he knows more about it than you and me do. So I take his word over yours.

Do you know when the Switch got a working version of UE4? 

Nintendo said from the get go that the Switch was going to be compatible with UE4. But then, support for it came much later. It isn't unreasonable to believe Square-Enix thought the engine was going to be supported much earlier than it was.
