Yup, I totally agree with you. There are many issues — especially in firmware — which we are not able to address. We do backport linux security patches but that gets harder with each release. We did indeed talk to other interested parties and attempted forward ports of the Qualcomm specific kernel features to LTS versions. I am not directly involved in that team anymore and sadly cannot tell you the exact reasons, but this failed to yield a usable kernel. I do like your suggestion of long-term support from Qualcomm which was unfortunately not possible for the Snapdragon 801. For Fairphone 3, this is hopefully on the table again (especially, if — as you are saying — other customers also show interest in LTS support). In summary, you make many great suggestions most of which we also attempted at some point. Unfortunately, the devil is often in the details.
