Why downloads have to stop when we start playing something that needs internet connection

[IcaroRibeiro]

This is so fucking annoying 

You buy a digital game and are basically trapped. Can't play your new game, can't play anything else online while your download keep running in background 

If internet becomes unstable when you are downloading fine, let me just turn off the online features for games such as Animal Crossing, Fire Emblem, Mario Odyssey and so on where the online playing is not mandatory
