my opinions about morality aside, someone pointed out elsewhere that mozilla specifically has an outsized relationship with the LGBTQ+ community, thus making it practically impossible for him to be an effective leader there
he himself actually literally said as much: "Our mission is bigger than any one of us, and under the present circumstances, I cannot be an effective leader. I will be taking time before I decide what to do next." [1]
it was reported on beforehand [2], but as far as I'm reading, there wasn't a serious outcry until 2014, six years after the donation, after he was appointed as CEO (and subsequently ousted)
as for politicians, I think they're by definition mealy-mouthed, and they often just say what they think people want to hear at any given time
