BlackRock wants to launch bitcoin ETF/trust: https://odysee.com/@TraderUniversity:a/blackrock's-big-bitcoin-bet:d

Probably very good for BTC value, but someone in the comments posted a picture of something: BlackRock gets to choose which fork it will use for its product if Bitcoin hardforks. Obvious and normal I assume, everyone would need to choose (or not choose = choose to hold both) I guess, but given that this product has the potential of becoming huge, wouldn't it give BlackRock a big influence on which fork will be the most valuable? The conspiracy theorist in me says that's their plan, and they will actively choose (maybe even create) a non-censorship-resistant etc. fork, and people who own bitcoin but don't know the reasons for Bitcoin's existence just go with it. I don't know enough to figure out if there's any risk whatsoever, or how big, of this happening, intentional or not. Feedback from someone who knows this field would be appreciated. (I don't even know exactly what an ETF or a trust is, although the discussion gives hints.)
