I had a good look for any sources now but it's the same media bullshit where every source links back to another article that links back to another article etc. There's references to videos but I couldn't find any videos. There's a reference to a UN investigation but it turns out it was an out of context quote by a UN spokesperson with no actual investigation or even any information from the UN. The more I look into this the more bullshit there is. The quote is published on the website "Business and Human Rights Resource Centre" which is primarily funded by private philanthropists like the Schmidt Family Foundation (set up by the ex CEO of Google Eric Schmidt). It was honestly just a waste of time, I could have just assumed it was made up.
