I don't think you get how or why ESG works.
When Blackrock makes an ESG fund, they'll look at governance issues like "Oh, Netflix has crappy governance", and then refuse to give them any money. ESG-funds focus on funds that have good environmental/social/governance records.
If anyone wants ESG-money, they have to match the baseline requirements of ESG-investors and what ESG-funds will offer. Otherwise, you don't get our money.

The other reason why ESG works, is this "G" issue. Companies that care about shareholders will, on the average, return more money back to shareholders over the long run.
Companies like Netflix who hoard power to themselves and overpay their C-suite are obviously wasting money anyway, and therefore make for crappy investments. "G", theoretically, is just a good idea for investors to think about _anyway_.
AKA: If Netflix are a bunch of assholes, no biggie. I can invest into Disney instead, who has a much better G/Governance structure. And Disney+ is kinda kicking Netflix's ass right now anyway, so I think there's a good chance I'd make more money.
If Netflix wants my investment money (or the investment money of anyone else in the ESG group/fund I'm part of), they'll need to fix their G/Governance issues. If for nothing else, for more fair compensation of their C-suite.
