Universal expansion and Black Hole Growth:

New study proposes expansion of the universe directly impacts black hole growth:

My question is why isn't any BH gravitationally decoupled from the large scale expansion rate, in the same way our solar system/galaxy /local group is also decoupled from the large scale expansion rate?

Or am I missing something? Yes I understand that this is hypothetical at this time, but why havn't those proposing this hypothesis, not seen it as I have?

Bump

from the article....Black holes grow along with the expansion of the universe. Hence my question.
