DAFs and GRATs are completely different vehicles. DAFs are beneficially owned by some 501(c)(3) and withdrawals can only go to arms-length, 3rd party 501(c)(3)s, with no reciprocity attached to the gift.

DAFs are a convenient way to gift appreciated stock (which is already a nice tax gift to the charitable wealthy), but fundamentally not a vehicle for passing money to your heirs.

Your article is about GRATs, which should be illegal.
