For this device, and for what it represents, yes it is immoral in my opinion. So people just bought it, knowing that the demand will be big enough, so that they can sell it as soon as they can. This is immoral for a community program designed specifically for people supporting Jolla. But this is just my opinion of course.

As with everything, be it second hand, it should lose min. 50% of its value, so this being used should be sold for 80 euros. And for what it is worth, I think no one should buy Jolla C from people who only bought it to resell it and make profit. They should get any other Sailfish OS 2.0 device, like Fairphone etc.
