literally nobody actually wants DeVos for any reason other than Trump says so.
That's false. Plenty of advocates for school choice want her. For example, National Review ran an article in favor of her in the past few days (should still be on the front page of their website). It's not just one article either, I've heard their writers support her in their podcast called The Editors. Ben Shapiro also spoke positively about her. Both NRO and Ben Shapiro have been and are still critical of Trump.
