Not only are privacy and data protection founding principles for both Mobifree and F-Droid, the use of tracking-based in-app advertising poses a moral dilemma as well. If someone wants to gain access to an app, but does not have the financial means to purchase it, they can use it at a different kind of price - their user data.
For me this reads as them explaining and condemning that dilemma, instead of considering it as an option for F-Droid.
