Ah, yes. The “let’s bloat our game size to bully other games off your SSD so you’ll be reluctant to ever uninstall it, because reinstalling it would be a big pain, that way you’ll play it indefinitely and give us extra money in micro transactions” strategy.
I would be curious if a large game would push people towards installing or uninstalling more. Personally I keep the 10GB indie titles on my Steam Deck and uninstall anything over 100GB.
Unless you are pirating the game and need to redownload it I wouldn’t give uninstalling it a second thought.
