Maybe it is - at least when you address people personally and you don’t know the person. One example: I know someone who needs to take medicine regularly with severe side-effects. It may happen that he says something to you and in the middle of the sentence he fells asleep. He might not be able to read through the posts of this discussion and find the information he is looking for. Nevertheless he would be able to use a Fairphone. Should someone like him not be allowed to ask the question he is interested in?
So instead of addressing someone (or someone’s post) directly I would write something like: “Some of the questions in this discussion were already answered in a previous post. So please read this discussion before asking your question”.
Back to the topic: I have a Fairphone 2 myself and I think the Fairphone 2 price is justified. But it is also a lot of money, and not everyone who is interested in a FP2 can afford it. So I am hoping that in the future they will be able to sell more Fairphones which can then be produced and sold at a cheaper price.
