Where did they break the law? Where did they admit guilt? Where were they convicted of any crime? Maybe they inconvienenced a few folks. But at no time where they ever found guilty of anything. Did you read the story?
As far as the "exploding" batteries, I am sure thay did that on purpose.
No one is that dumb to believe they are.
Also, I think it's pretty smart marketing to try and figure out what people like. Maybe a little submersive in their practice, but how is one to venture what people like if they don't do the research?
Also, your title is wrong. It isn't a 150 fine. That's per person which is 7 million x 150.
