@Douwe, one of the moments where again I think that Fairphone is failing to presenting itself properly (also thinking of the phrase: ‘do good and talk about it’).
That information does not belong just into this community forum, because only the very interested/enthusiastic/disappointed people will come to read it anyway. And then it is still a lot of random digging to find this juicy-parts-post of yours.
What belongs into this forum is a reference to this information on the main Fairphone page. But looking here Fairphone | The phone that cares for people and planet I cannot find anything like this.
Also I think that a newsletter regarding FP1 end of life is not enough.
People having changed their mail account might not get the information plus it has a feeling of trying to dodge bad press when the blog does not contain an entry. In that entry you could explain why you decided to stop the support - or, if that is the case, why support is not possible at all - and that in more detail than in the mail and community forum entries. For example someone posted somewhere that FP1 exists in so small numbers, that continuous production of spare parts would be an environmental impact not outweighed by its benefits. And why is that? Because nobody in the industry has ever really tried to standardize batteries and that is the real disaster. Also in that blog entry you could explain whether back in the days when FP1 was initiated nobody thought about that situation or whether there where reasons why to expect a different development. And you could explain your measures how to avoid a similar fate for FP2.
I think people like simple answers, because they make decisions in life easier. But sometimes things are a little more complex. So for those who really want to know it would be interesting to get the information easily and intuitively.
