The sustainability issue is difficult, there are other points that are not (yet) sustainable even with Fairphone. But it is fundamentally a problem because, for example, the mining and trading of necessary minerals in the mines of the countries of origin is not completely fair... I, too, have to live with this, but as an owner of the Fairphone for several years, I can give it my full praise, at least as far as its functionality is concerned. Apart from the fact that the headphone jack never worked right from the start 😉....
