I think that's fair enough: an organization that acts as a security blanket and deus ex-machina to help the investigators out of trouble will undermine the horror a bit, and could be a long-term problem, especially in a campaign.
On the other hand, if all it serves as is a quick-and-dirty plot hook in the form of an organization that doesn't have much money, power, or influence, I'm sure it would be fine.
And then, on the gripping hand, there's the Carnacki Institute from the film Judas Ghost (2013), which serves as a sort of investigator organization in that film, but reveals itself to be a very remote and mysterious organization that seems to be playing a long game against Eldritch Horrors in which its investigators are mere pawns that can be sacrificed when needed. It occurs to me in combination with the related discussion on Bad-Guy Organizations that investigator organizations - good, evil, indifferent - can serve a useful purpose in enhancing the sense of isolation, horror, and alienation in the game by being amoral, aloof, faceless, nearly eldritch horrors in their own right, anonymous entities that do not actually have the investigators' best interests at heart, nor even a heart at all - they organize, direct, and sometimes even help the investigators when it suits them, but the organization ultimately walks alone, and the investigators and other human life are no more than disposable assets and collateral damage in the way of the organizations ambiguous and mysterious goals.
