From what I've heard the number gets so high because duckduck blocks the app from gathering data. The apps keep pushing requests since they're not getting any response. In reality the non-blocked requests are less frequent. Don't quote me on this, just a thing I read on reddit.
But yeah I have duckduck as well and it freaks me the F out seeing what apps are trying to gather. It's sickening.
You can choose not to preload the game, can't you? So it's up to the individual. Besides, why wouldn't you want to preload the game so when it's released you can just hop in? I don't get your angry reasoning here. If you're gonna play the game then the storage is gonna be occupied either way. Lol
