Why Blackrock Bitcoin Spot ETF can damage BITCOIN

After so many articles about how Blackrock Bitcoin Spot ETF is fantastic and a great thing that can happen, I tried to search if there are negative things about it, and I found something scary, at least for me. (I'm not a tech guy and I am not sure this can happen.)

So, from what I understand, in case of a hard fork (can they hard fork bitcoin purposeful?) they get to decide which fork to go with, therefore they decide the future of Bitcoin.

So we all know that government and other powerful people control gold, diamonds and other stuff, are they trying to do this to Bitcoin as well? I would like to hear the opinion of people who know how a hard fork can be possible and if it can happen in this case.
