Some genuinely have I'm sure, but a lot of the blame is on Nintendo. I think you could argue that Nintendo resents more 3rd-party publishers than they get resented themselves. Final Fantasy VII was a big fallout moment for Square and Nintendo. Square had ambition with Final Fantasy VII. That ambition would've required about 30 64DD disks instead of 3 CD-ROMs. Nintendo basically told Square not to come back after that. While Square still supported Nintendo platforms, it was to a much lesser extent than PlayStation.
EA was going to have an "unprecedented partnership" with Nintendo, but then they all but abandoned Wii U after 2013. You could say similar things about Activision. I don't think EA and Activision resent Nintendo in a traditional sense. I think they're just salty that it's far harder to run their games on Nintendo consoles and sell their microtransactions.
Nintendo tends to keep third-party publishers more in the dark than Sony or Microsoft. That can cause some friction. And let's not even get started on Nintendo's very greedy licensing policies during the NES days.
