I think it was mostly base on Nintendo being a dick to square during the nes and snes era. With Sony finally being an out from the Nintendo.
I think it all started when square wanted to release ff2 and ff3 to foreign markets and nintendo basically said no.
Then Square wanted to bring ff5 to western markets but Nintendo said no westerners were to stupid to play complex rpgs so we got FFMQ instead.
Then Nintendo told Square they were gonna make a snes cd and to make secret of mana into a cd game. Nintendo scraped the cd.
Then Nintendo would not allow Square to use on of the larger snes carts even though they allowed enix to.
Then Nintendo basically tried to steal all of Square's work on SMRPG and would let Square publish it in Western markets.
Then Nintendo did not give Square advance n64 dev kits basically telling square they're not prized as a 3rd party.
Then Nintendo decided to switch from cd and back to cartss
Then Sony went to square and gave them tons of benefits.
Square accepted Sony's offers and tried to convince other third parties to follow them.
Hence the hate between the two.
Nintendo was pretty much the biggest jerk anyone have ever seen during the nes and snes days. The problem was that they had such a monopoly in Japan that the third parties needed them. That's why everyone was more than glad to leave when given another sensible options.
