Nothing. That's why we need enough individual like minded people who run their own nodes and make their own decisions, or Bitcoin fails.

Would love to see Nayib (El Salvador) run a huge node.

"Freedom is never more than one [block] away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in [Bitcoin] where men were free." - Ronald Reagan
