The only way to get this EA background service to stop auto-opening over and over in my case was to close Steam, since the game I was playing, Battlefront 2, was installed through Steam. I'm not gonna close Steam just to get this garbage background service to stop running. Steam already keeps installed games updated on its own, so I don't need EA's worthless background service to keep my EA games updated. It's clear the reason they refuse to make it easy to turn it off is because it's collecting data in the background.
Had to follow this complicated guide I found on a different page (I can send a screenshot of the guide if anyone wants it) that involves making a scheduled task in Windows that automatically terminates the EA background service if the EA App isn't running, and prevents it from starting again. This is what the app itself would be doing if it wasn't developed to collect data from the user's system.
