> CFOs have other means of doing that, in better ways than a simple blog post.
I believe this CFO agrees with you. Most of the "celebrity cause du jour" tweets are just that, tweets. At least at the end of this post he listed groups that he's donating to
[1] NAACP Legal Defense and Educational Fund
[2] Advancement Project
[3] Color of Change
This may not mean much to you, but at least he's claiming to put his money where his mouth is.
