Among the reasons why I bought the Fairphone 2 is its engagement about open source. I wish with this phone to rely the most possible on free software and to control everything on my phone. This way, I'm not obliged to always buy new hardware because of software updates even though it's still working. Also, I can use the services I wish like my own cloud (powered by Owncloud haha!) instead of Google's, Apple's or Microsoft's clouds on which I don't know what is happening. Good news: Fairphone released its own open source operating system based on Android called Fairphone Open.
