This is huge, because it means that anyone buying an iPhone or apple product going forward is knowingly supporting this behaviour.
I fully expect this to be the ruin of Apple.
This seems like a bit of a reach tbh. It's no doubt hopefully huge, but by buying a product you're not implicitly agreeing with every or any element of internal company politics that occured during its production. I buy Macbooks because I tend to like most aspects of them, but use mostly Pixel phones, does that mean I support literally anything Tim Cook or leadership does to produce anything else? Not really, I just use the tools that work for me.
This is human communication. If you make an ethics-based decision and communicate that with friends or family, they then have to make the conscious choice to continue supporting the business with this practice or seek alternatives.
People who care about humans will support businesses that care about humans.
