Do you have any evidence to back these claims up? (genuinely curious)
ETA: I agree that you did not say this was happening in your original comment, but it seems to me your comment implied that these companies were actually influencing major decisions (since that's the topic of the OP).
Blackrock is a major institutional investor in just about every company, so they have press and backchannel effects. I assume similar things happen with e.g. vanguard and big ibanks. I know Jamie Dimon has been railing about RTO for a while.
