Apple has begun its push for sustainability well before Greta Thunberg by reducing the carbon footprint of its products and not using toxic materials for its devices. Since climate change became a major political issue, Apple started to highlight its contribution to the protection of the environment.

Yeah one of the very few if not the only in Appleland. I still remember Apple tweaking the external shape of iPhones ever so slightly just so that accessories are incompatible between generations. And removing accessories without lowering the price doesn't make economic sense (for the consumer) either. Hypocrites.
