You misunderstand again. Bob isn't Alice's spouse, he's Alice's employer. Bob legitimately gave Alice access to confidential information in order to do her job. But, unknown to him (unless he intrusively investigated her personal life), Alice could be blackmailed into abusing that access because she cheated on her spouse. Bob isn't "complicit" or "culpable" he's a victim. I think you're overconfident in simple security measures and have a poor understanding of human security threats.
