"99% of the hashrate can't stop a non-censorious 1% of hashrate from getting transactions into the chain"
Pierre Rochard said this in an episode of the TFTC podcast (link below), but it's not true.
Any entity with more than 50% of the hashrate could kick out the other hashrate by refusing to build on top of their blocks. The minority hashrate will see their blocks don't stay in the chain and they will be forced to shut down as they don't earn anything from their mining.
So then we would have a "CEO of bitcoin", the leader of the hashrate, who decides what transactions are included.
And there's nothing the nodes could do about it.
That's why it's critical for the (economic) nodes to main a relentless "divide and conquer" regime so that the big miners cannot organize themselves like this. This is a critical issue in any big argument about Bitcoin, like the blocksize war and the current podcaster thing. And more private hashing (e.g. multiple hashpool.dev pools nostr:npub16vzjeglr653mrmyqvu0trwaq29az753wr9th3hyrm5p63kz2zu8qzumhgd ) is just one of many things that can help this.
