You have long stated that Bitcoin Core is in control of the Bitcoin Protocol. You're being proven wrong on this front as well, which is pretty much the same exact concept.

Bitcoin Core was delegated power.

And now that they are saying they are going to remove the op_return 80 byte limit people are switching over to Bitcoin Knots in protest. Bitcoin Core was never in control of Bitcoin.

Mining pools are delegated power: they can't attack/control Bitcoin.

Most of Blackrock's power is also pure delegation.

You seem to greatly struggle with this idea that when people fuck around they find out very quickly. The balance of power at the top is not a pyramid; it's an inverted pyramid that can topple over for like any reason. You just think it's an easy job because they are experts at balancing the teetering pyramid and make it look easy and stable.

Blackrock is in control of very little. What they are in control of is delegated to them by their benefactors. They do not make big waves. They are masters of the Butterfly Effect. Small nudges that lead to big profitable outcomes. Larry Fink is the face of a single hedge fund (in a sea of hedge funds). His power is even more limited than Blackrock's.
