They do not state anything like that; that's the entire problem with that linux-libre patch. It is removing a message that informs user that their computer is at risk without an update, because they don't want people to know, because if they did most people would choose to install the proprietary update to the proprietary microcode they are already running, and that would expose the existence of that microcode, and the FSF's utopia only exists in the minds of people who aren't aware of all the proprietary firmware they're running anyway.

It's all a big lie. There's proprietary firmware everywhere. The FSF just doesn't want users to know about it, so they can live happily in their blissful ignorance believing they are freer than everyone else.
