Eventually, a representative of the Canadian company confirmed that the whole story was just meant to be a joke about IE6's incompatibilities and was not intended to be taken seriously as actual news. However, even if it was meant to be a real press release, something else about the "study" should have tipped off reporters: The release stated that all of the interviews for the study were conducted through free online IQ tests. You know, the ones you've probably filled out by clicking on a banner ad somewhere, only to find out that you were in fact a genius. There was no mention of whether the data collected was verified in any way, or if it was just something your grandma was filling out with random answers because she thought she'd win a free iPad.
"That's a very impressive anus, Mr. Google. But I don't see what it has to do with goats."
And just in general, be wary of any story that tries to tie some broad population trend to IQ (like the election-season classic showing that voters for one party have higher IQs than the other). Ironically, the only people who think intelligence is that easy to measure and quantify are the stupid ones.
