EA had their own reasons besides it being a simpler financial decision. Bernie Stolar said EA wanted to be the sole provider of sports games on the DC, SEGA didn't agree. It is also coming to light that EA had stock in 3Dfx and SEGA did not choose them to power the DC so EA was salty.

Square never developed for a SEGA console so that was no blow to SEGA Square not being a developer.
