if it weren't these competitors, who then would expose these things? the company itself? hardly.
that's called self-regulation of the market and if this story were entirely made up by competitors, AX would not get in panic and stop production and recall the product after they got called out on that.
safety? nobody knows. It could destroy your brain cells and most people wouldn't even notice it. Actually, nobody knows, and this is exactely what is most disturbing.
