It’s not “WWF is benefitting from…”, it’s “WWF helping facilitate trade in polar bear fur, investigation reveals”. “Investigation” here refers to the article published in guardian. The proof is the lobbying WWF did. They’re complicit in allowing this, sadly. Other NGOs stood strongly against WWF: https://ssn.org/app/uploads/2019/03/Cop16_PolarBear_EN.pdf

That’d only create a black market and illegal hunting. No one needs a polar bear fur rug / coat.

There are links all over the article

WWF said in a 2013 statement: “If, at some stage in the future, polar bear populations become so diminished by climate change and habitat loss, and/or if international trade presents a greater threat, we would want to revisit the Cites listing issue. But we’re not at that point.”

Yeah lets wait until it’s too late for the species
