She has already given more to SO before the controversy than all of her critics combined (including you).
She would not say whose decision it was, but there is wide speculation that it was Trump (of course, who else would the msm speculate that it was - but in this rare case, they might be right).
Regardless, DeVos argued vehemently against the move. She has more money than Trump ever dreamed of having and could have walked away long ago. But she has a rare kind of self-effacing character along with a strong desire to make a difference in the educational system of this country. Thus, she endures the attacks from those envious of her wealth as well as those who foolishly presume to categorize her based on limited information (that is your special ability).
This person has given over and over of her time, effort, and wealth. And she has more genuine concern and actions for the handicapped, disabled, and afflicted than any one of her critics.
