Why do you need to leave it running? Why would you have it running if you’re not playing a steam game or using its overlay and controller features? You’re inventing problems that don’t exist because you seem to not understand how to use the software. You open it when you want to play a game. If it starts updating stuff, you pause it or cancel it. Why would you blame steam for developers pushing updates in the first place? Turn off updates, boom problem solved. Like yeah, gog is better in their DRM stance but galaxy is not great software, and updates are important for modern games that ship largely broken and unoptimized, and the gog offline installers do not make updating easy. You’re holding a fork and complaining that it makes for a shitty knife, like yeah bud, you’re using it wrong.
