There's two "Black Lives Matter", which is handy for their motte-and-bailey tactics. There's the slogan "black lives matter" shouted by your common normie who dislikes police violence, and then there's the organization Black Lives Matter, which is a far left, black nationalist, Marxist organization that wants to abolish the police and prisons. It's not well known that there is indeed a central group called Black Lives Matter, most people think it's just a slogan or hashtag.
All of those donations are going to this organization which should fucking terrify you. It's like corporations donating tens of millions to some gay rights group which includes NAMBLA and some pro-bestiality group as prominent members.
