ETA: I missed that you seem to be saying it was 100% effective _for you_, I misread you as saying it was 100% effective in general; my bad.
No it isn't. For instance I recently tried to uninstall YouTube and my Android phone wouldn't let me (I know that I could move to a different distribution, but this is not high on my priorities list or something I want to mess with when I'm trying to relax, and many people wouldn't know where to begin). I've had periods where I uninstall and reinstall Twitter several times in a day.

It's helpful but it is not a panacea
