Charities are in stiff competition with one another. They need to employ people at the top who know what they are doing, or they would have to rely on the local Bring and Buy, or people collecting money from the neighbours in house-shaped piggy banks.
Communicating with huge numbers of people needs skill, as does managing budgets of millions of pounds. The CEO doesn't have to be a saint - just to be good at what they do, and bring in the money.
I choose my charity donations based on how far I prioritise the charities' aims (which is obviously difficult when there are so many good causes) and whether their deeds match the aims. I have recently stopped donating charity shop items to Oxfam. I was willing to believe that the revelations about the recent scandals were a case of 'bad apples', but when they withdrew a game that celebrated influential women because it 'upset some trans and non-binary staff' it was a step too far.
I would have withdrawn my support when I found out anyway, but another thing that a good CEO will do is manage the PR of their cause, and IMO this was a spectacular fail. A good one would have handled the story better, both before and after it broke.
