That's even worse, since VT is a civilian institution...I think we went over that for PoS back in the day[/spoiler:322df7f9c0]

Well, it's in Vault 87 according to this guy:

And we don't know yet whether they originated there or whether they took the vault over.
As for VT being civilian, it's true, but it was part of the military-industrial complex, and with the whole Safehouse Project part of the Enclave's experiment, anything could happen. And at least, unlike FOBOS, they didn't acquire FEV secretly from the government but as part of the government's plan.
Not that I'm making excuses for Bethesda, but Vaults being experiments was one of the worst ideas in the history of the series anyway. Still, at least in FO2 the game didn't focus on it so much and the experiments themselves weren't over the top (although some of the Fallout Bible ones were - dunno if they came from Avellone or from Cain's original design document).[/spoiler:322df7f9c0]
