This makes sense for the US Government. But at the same time, it makes more sense for me - as a US citizen - to use Kaspersky. The Russian gov't doesn't care about me at all, so I have little to fear from them. But I do fear the NSA because I am subject to the whims of the US government.
What if your PC gets enlisted in a state sponsored attack against the US? Or is used as a proxy for an intrusion? Or... so many other possible scenarios...
