I don't think it is that nefarious at this point (could become at some point). I think they see a lot of demand for bitcoin both from a younger cohort who they don't have as customers yet and their existing customer base who want to "trust" someone to hold their Bitcoin for them.

That's another reason why it is important to own a node.

Sadly I believe miners can be taken by TradFi... Node owners is a bit different...

I can imagine a fork happening because of this.

Most important is, there is a lot of ideology behind Bitcoin. If they come in and take over. Well just created another Bitcoin to keep things as they are now.

They can't take our minds.
