An unstable personality that hates the US saying the US government would stage a suicide is much more likely to actually kill themselves than your regular run-of-the-mill evil billionaire with powerful enemies saying nothing about how they will die.
I don't think Mcafee really thought things through enough to come to this conclusion.
It is also what folks with absolutely no intention of killing themselves would say. Sure, you could parse out situations where they might and you could probably make someone's life so unimaginably miserable that the would eventually turn to it, but these are fringes.
