The endorsement of the drug is the crux of the hypocrisy because obviously she didn't come out until she and her handlers had figured out a way to maximize her ability to profit from the situation.
If she merely continued to make unhealthful recipes that she can't eat, it would merely put her in the category of someone to snark about rather than someone who is repulsive to me.
Her protestations of "privacy" ring false since she agreed to go public when it was most financially beneficial rather than risk a hit to her empire when she had nothing to gain and something to lose.
I am old enough to remember when Betty Ford came clean about her addictions as well as her breast cancer. She had nothing to gain - helped many people with her honesty and in fact helped fund a world class rehab facility.
