The recent buzz about DoJ putting backdoors in OpenBSD's IPSEC stack was, even if you buy the totally unsubstantiated and bogus buzz, in order for DoJ to monitor their own networks; ie, even if you believe the crazy people spreading that FUD, there's no claim that there's a public-facing backdoor in OpenBSD.
It doesn't seem reasonable to me that we should spend months up in arms about the government backdooring projects every time someone 5 degrees of separation away from a major project makes a claim.
