There is an interesting and (imo) humbling take I heard about this from a local radio host who was asking the same question ("what motivates somebody to expose their true value?"). In this case, the host brought up that several (all?) of Neil Young's children suffer from medical maladies, which may cause him to be more sensitive to situations that he believes could cause them undue harm. I still disagree with Neil's position and decision, but I found that this really helped humanize him in ways other pundits have missed.
