alt Hacker NewsThere are two cases: I am uninstalling because I never want to use the app, or I am uninstalling because I know I currently don't need the app and will reinstall after 6 months when I do.
An example of first is a trial of an app but you don't like it in the end, an example of the latter is a game that you might want to play with the same settings later.
Now, I want the option. In the first case I don't want these inert files taking up disk space and in the second I want to have those files.
I stopped trying new apps as often, because I don't like how I can never really go back to a state before it was installed, unless the developer actually put effort into not spraying files everything and not leaving a trace once gone. I appreciate these developers very much, and am more likely to keep using their apps. The most junk an app install puts on my system, the more likely I am to want it gone.
