I don't think they hate each other. Many developers at Nintendo own Playstation consoles and I am pretty sure a lot of Sony staff owns a Switch.
But I think it's natural that both companies (as well as Microsoft of course) pay attention to every move the other takes and act accordingly. For instance, there are rumors that Capcom's Monster Hunter Rise was supposed to ship this winter - just in time for the PS5 and XSX launch. What a coincidence, right? It got pushed back due to corona, however, but to me it's pretty obvious that Nintendo suggested this release window.
On the other hand, Sony has always and will always copy Nintendo when they do something good, with haptic feedback being the latest thing.
