I like to keep it simple, the Orokin "broke" the warframes, more mentally than physically, but the Tenno, thanks to the Zariman experience, were able to connect with them (Warframes), so it feels like the "regular/prime" frames we use simply allow the Tenno to "use" them, not only because their minds are "destroyed" thanks to the orokin, but because they somehow relate to the Tenno in some way. I prefer to leave this "lobotomization" theory aside and belive that the Umbra is an exception thanks to his hate against Ballas, and in fact anything that lives, because of the loss of his son (BTW, he may not be the only exception). Also, as stated in the quest, Umbra Ex. later accepts the tenno and allows transference.
