This is a completely different thing. The article is talking about donor advised funds, which are 501(c)(3) public grant-making charities that allow you to donate cash or non-cash assets. The DAF then allows you to recommend grants to other 501(c)(3) public charities. 501(c)(3)s are completely barred from participating in politics. Dark money runs through networks of 501(c)(4) organizations. They're a different beast entirely and can participate in politics. You don't get a tax deduction for donating to a 501(c)(4).
