Can't trust anything these days. :/ I have several Supermicro machines on my network. The Intel ME backdoor is probably still worse than the SM one though. Sadly there does not seem to be any real privacy these days. Everyone is out to spy on us. Corporations, and governments.
Some people are denying the validity of the article, but IMO there has to be something that causes info like this to come out. I doubt it's 100% made up. Unless it's like a disgruntled employee or something.
