I'd be willing to accept that if they behaved like many of the other programs and offered you the ability to turn that functionality off. Other programs doing it without the option to turn it off doesn't make it right. For any of them.
Steam is the only one I want running in the background all the time because 99% of my games are there, as are 100% of my friends. I like the mission GOG is on for DRM-less games, but I don't use it enough, I should be able to set it to actually close. Epic... Epic is barely a gaming client. Regardless, Epic actually DOES allow you to turn that feature off. Amazing how even a [Removed by CM] such as Epic can do that for us.
It's stupid and lazy programming not to allow us to turn it off. If I want or need something running in the background I will let it run in the background, otherwise when I want something to close, I expect it to close as the "close" button is supposed to do. If by "driver control center" you mean something such as Nvidia Geforce Experience, you do not need that running at all ever. If you would like the features of it such as Shadowplay to be available, sure. Otherwise you can quit out of it entirely and be fine. But Nvidia should also put the option to not have it minimize to the system tray.
As for Origin, and soon to-be EA Desktop... they should definitely have it considering barely anyone uses them anyways. Why would someone want them running in the background longer than needed? In my experience with EA Desktop it even seems it wants to quit completely more than I want it too considering how often it loves crashing and needing to be restarted.
So once again, I hope EA can find it in their sad, dead, empty hearts to fix this issue and not be the absolute *-stain of a company they're seemingly on the march to continue being. I won't be surprised if they decide to keep it as-is, but then I might just have to find other avenues of playing EA games without Origin or Desktop. I hear Sims 4 runs perfectly fine without any EA programs running.
