Blackrock is shareholding on behalf of individual investors. The amount of decision they can wield is pretty constrained. If I hire you to do my shopping, you can't just cross items off the list because you want to power trip on the butcher.

Furthermore, even if I buy into the hypothetical that Blackrock would dump a company from its portfolio over ESG, how much would it actually drop the price of the stock if the fundamentals are the same? Is the problem that there are not enough greedy investors on Wall Street?
