Given that it's literally an upscaled Starfleet runabout with a different nacelle configuration and we've seen Oberths in both Starfleet and civilian hands (indeed the Raven itself is referred to as both the USS Raven and the SS Raven at various points), I don't see any reason to assume that.
However, that's a moot point as the website specifically discusses a Starfleet variant (designated the Raven-class) of the canonical Aerie-class or Raven-type civilian vessel which sidesteps the issue IMO.
I’ll assume it when I see it being flown by actual Starfleet officers (besides officers who found a junker to use to escape.) And that website can say whatever it wants; it doesn’t change the fact that none of its information is canon.
