BlackRock and State Street biggest funds are all passive and are indistinguishable from Vanguard. All 3 offer active investments, but their passive portfolio dwarfs the active ones.
BlackRock != BlackStone, if that’s what you were thinking of.
Then enlighten me about the, presumably, massive difference between BlackRock and Vanguard passive funds. It must be something so huge that they are both in the index fund/passive fund category and yet “can’t be lumped together” because it seems you’re the one who doesn’t know much.
