There is a lot of hedging in DeBord's article, and he never flat-out states that the EMFs in EVs do cause cancer, just that they might. This is a fair subject for scientific research, but no one has had enough time to determine if EVs are any worse than hair dryers or cell phones in this regard. DeBord admits that "automakers have tested their vehicles for EMFs (conventional cars as well as hybrids and EVs), and found them to be within accepted limits." Of course, there are some things we know for sure: that gasoline fumes are tremendous health hazards and the geopolitical reality of gasoline dependency isn't that great either, but that headline isn't as hot.
Also, way back in 1999, the National Institutes of Health issued a statement saying that one researcher who claimed that EMFs and cancer were related had falsified data (thanks to Paul Allen's comment from 18 months ago for that link).
