Let's look at the actual statement made by Blinken. He said that 100-150 Americans remained in Afghanistan "who wished to depart." That means that however many Americans remain there, the vast majority are there because they didn't want to leave. This includes people who work for humanitarian organizations and those who have familial ties to Afghani citizens.
The Taliban are not preventing any American who wants to leave from doing so. But Miller's little "news" story makes it seem as though there are still thousands of Americans, frantically beating their fists against the walls of the prison that is Afghanistan, wailing and screaming to get out.
And of course, David's widdle tantrum ignores the fact that none of this would have happened if Trump hadn't opened his legs for the Taliban in the first place.
