The main reason I use F-Droid is because, it's closer to a Ubuntu style repository, that I can assume it's basically open source, maybe some licesning restrictions, certainly not like 'free' apps in the appstore designed to generate income for the author. And it's almost always me getting stupid apps that should just be part of the OS. A Calendar app, I can use without having a gmail account A note taking app A sound recorder etc.
