People like to criticize Dropbox's appointment of Condoleezza Rice for much more substantial reasons than American party politics. 'Drop Dropbox' [1] offers an overview that, while biased, does address that accusation in particular.
A lot of my personal moral concerns with Dr. Rice's appointment are as a result of actions she condoned or advocated for during her time in government. Don Knuth's letter to her in 2002 expresses my feelings on this topic much better than I think I can myself.
For what it's worth, that page gives Dropbox and Apple the same score. (5/5: 1 point on each of 5 questions.) If you find this surprising, check out their evaluation criteria; they might not be the same as yours. I find the 5th criteria somewhat arbitrary for instance, although I sort of see what they're trying to do with it.
Have you seen Apple's designs, code, and fabrication plants? Why wouldn't Apple capitulate to possible demands to claim privacy, while actually spreading compromised devices?
