We have decided not to disclose the names of the people nor companies in this email. While we certainly have the legal right to do so (the email is a public document), we are cautious about any indirect problems this would cause for the people involved, especially since this email may be designed by a competitor to inflict damage against them.
If we discover any evidence that supports any of these claims (a person coming forward with a report, a company HR department confirming that an investigation is being conducted, etc.), we would update the report with the appropriate details. However, the evidence we have found so far points only to this being a hoax.
Finally, we believe and hope this manufacturer pursues all legal options against the perpetrator as these types of actions are extremely dangerous and malicious.
