That doesn't normally buy you a murder conspiracy unless there were overt acts that furthered a murder plot and you need a felony in there somewhere. There's no law against "economic harm" as such, but there are certain ways to compete unlawfully.

Rather, the article says there's a rule against disparaging other products. That sounds more like policy, rather than law, which is not usually a felony. It also merely says they're 'investigating', so there's nothing for us to even look at until we see whether or not they actually bring charges against anyone.
