This article brings many things to light. Now, if someone works for a company who builds platforms or writes software for a program, this person would have full knowledge on using that back door for specific programs. Which means, not only would NSA would have access to the programs in your computer, but also if these particular geek who helped write the software scripts or was aware of the how the back door entry could be made.. If this particular programer is not ethical or honest.. could explain a lot of hacking that goes on.
Its not the NSA I worry about entering in through the back doors.. its the geeks with criminal intent, or the geeks who associate with those who have criminal intent.
