If the company was a mine, or some other business with a large on the ground operation in places where modern slavery is a thing, then I could see a statement like this holding water.
But you guys arent a mine, or a lumber factory, you provide online gambling services. I'm really struggling to see what they could possibly do one way or the other in terms of modern slavery besides the usual like auditing your vendors, but again, hard to imagine them having vendors that employ modern slavery given their market.
