I feel confident no permission is required to publish these facts if they are converted to a different format. I suspect, though I am not sure, that it is permissible to distribute them in their current format; either by not being under copyright or because permission was granted. While not definitive, the lack of copyright notices with the tablebase files on Bob Hyatt's site is suggestive of this.
