@JacobVR, you are right and many people agree with you.
Even Fairphone agrees with you. That is why they have invested resources in updating Fairphone 1. We don’t know yet whether anything will come out of it.
Meanwhile, you can try the unofficial update which is compiled by a community member. There is even a nice and easy tutorial how to install the unofficial update.
However this thread is about the future of “Fairphone Open Source OS” which is only for Fairphone 2.
