So they are sueing him over some words on a forum??? Errr oooook....

No, they're suing him because, as a former employee, he would have had to sign a Non-Disclosure Agreement which means he agreed not to discuss the company, nor its products, with anyone outside of it, or does not have a legal reason to know it (i.e. investors). If he is an investor, as he has apparently claimed, then he does have right to air grievances about a company that has his money, however, that just means he's an idiot because revealing information such as this would depress the share value; on the other hand, that may be deliberate, with the intention to buy up more stock at a cheaper price, but that would be classed as insider trading and he'd be in even bigger trouble for breaking criminal law, not just be in breach of a civil agreement as an ex-employee.

Either way, he's showing himself as being none too bright, if he provided enough information to positively identify who he is.

sued? thats a bit of a wild statement. I don't think they have sued him. I would correct that for sure unless they can show you a court order. its too fast to have sued someone over this.
as for digiguys, based on what this guy has said, investor, ex employee or not, I tend to believe him. by coming down on this guy in the way they did, they just validated his claims.

This guy was telling the truth. More info about it from more sources is about to be brought to light.
