Disingenuous, seems a bit presumptuous. Could be a sincere communication problem due to the way you and they scope IE differently. They  seem to be focused on 8 and below, where you focus on 9 and up. If they had said we don't support IE&lt;9, the above is pretty moot. If their analytics show a majority of IE is less than 9 (totally plausible), then for them IE support is (effectively) support for old versions of IE.
