I'm afraid I don't believe that about the government never doing anything to benefit people because they want to benefit people. Not that I'm so naîve that I don't think there's political calculation involved in anything.
But Apple and for-profits and some non-profits? It's the greed almost always. The fine woven is ridiculous. At first I asked myself, "isn't leather made from by products of food production that happens anyway? Well, I guess the leather processing is bad for the environment." But isn't producing "fine woven" probably bad for the environment, too? Vegans could always purchase a non-leather case. So it can't be just to please vegans, right? My conclusion: for the extra profit.
I mean you can make that conclusion the goal of anything a corporation does. After all, that’s the only thing they are chartered to do.
That said, the stars can align. What’s good for the environment can also be good for profits.
Is that the case here? It is impossible for us to know fully. Apple has a huge profit margin on their cases. Is that margin the same or larger on the new vegan cases? Do they anticipate the same sales volume as before? They could end up net neutral or worse off or they could end up better off.
Either way, if you want a real leather case there are tons of third party case makers out there. Apple for the longest time didn’t even sell cases! In my view the only real way to use an iPhone is without one.
