I really think that they will have to be really careful with their moves when trying to take the control of Bitcoin.
Blackrock can't take the risk to rekt its customer while choosing the wrong fork etc...Selling ETFs doesn't create more BItcoin users, therefore it does not give you much weight in the debate

So yeah they will surely try to influence the debate, to pay some drivechains influencers and other zealots and idiots, and it will surely make some damages, maybe big ones.

But ultimately there is a way (most probable) on which the memers win, because they support the best Bitcoin possible, which is the most uncontrollable Bitcoin.
The suits will not win this fight by creating a fiat version of Bitcoin, because the market already decided that fiat is worthless against Bitcoin.
We will win by KO if they fight.
