Reply: This is definitely a problem for the views that many philosophers have put forward. As Williams stresses, it isn't on its own a problem for the vagueness solution to the Problem of the Many, but it is a problem for the conjunction of that solution with a widely endorsed, and independently plausible, explanation of the Sorites paradox. At this stage, i.e., as of 2014, there are no published replies to Williams's argument. In his dissertation, Nicholas K. Jones (2010) argues that the right response is to give up the idea that speakers typically confuse Definitely, there is an F, with There is a definite F, and instead use a different resolution of the Sorites.
