Sort of. The rebuttal (by Flandin and Friston) suggests that properly-applied parametric statistics of the kind they favor are valid. Eklund et al. wouldn't disagree with that because their own findings support it, but they would point out that not all researchers necessarily adhered to the conservative statistical approach that F&F discuss. More specifically, both sets of authors describe the importance of using a conservative "cluster defining threshold" to identify spatially contiguous 3D blobs of brain activation. Eklund et al. use their findings to raise the question of whether the bulk of fMRI reports were conservative in this regard.
