From CNET's Molly Wood re Tobacco/Cellphone industries parallels:
"Unfortunately, studies start to appear showing that the product might be harmful to its users--even cancer-causing. The product's manufacturers deny the presence of any danger and even spend millions of dollars trying to discredit the research that points to problems. Then, an insider emerges, seemingly with proof that the product could be dangerous. The industry agrees to publish warning data about the product, but continues to maintain that the product itself is safe for use. Lawsuits against the product's manufacturers are filed, but all are dismissed. Industry analysts know that any case that does succeed could start a domino effect of future lawsuits, which keeps the industry determined to maintain that the product is harmless, despite increasing evidence to the contrary."
