I mean, what exactly does anyone think Q penetrated and disrupted?

It prevents any meaningful action. Also, it keeps those who could still actually resist into delusional state of thinkging that all that's happening somehow happens for good. Trump has betrayed every promise he has ever given, yet, blinded by the lies of Q his base still believes in him somehow.

About the closest any of the trolls can come to a justified analogy is that Q is meant to keep anyone from taking action.

Yes, that is exactly what Q is doing. Does it seem like not a big deal for you? The task of Q is to hold off those who could actually resist. Normies won't resist. Normies do not even need to be more brainwashed beyond the point they already are. Q is not for them. Q is for those that have broken out of mainstream web of lies... only to meet next web of lies.
