Yeah but the question is where's the proof that they actually put that into practice. Because all large corporations are full of ESG and greenwashing messages on their websites but we all know the reality is different. Missions statements are cheap.
Tony's Chocolonely is an interesting brand, because its origin lies in a Dutch TV show investigating consumer goods. At some point, the presenter ("Tony" [1]) decided to sue himself for buying slave chocolate, and then decided to see how hard it actually is to make slave-free chocolate - and Tony's Chocolonely was born.
As I understand it they're less strictly idealistic than they used to be so as to be a profitable business, but at least it wasn't an attempt at fairwashing an existing brand.
