Two thoughts, I wonder if the they are anything like those “charities” where the top people get lots of money, fly private jets and stay at The Four Seasons. Also, with the mindset of the people involved it is easy to cross the line from legal advocacy to terrorist enabler. If, say, they fund a “spontaneous” protest where paid protesters kill somebody. No, paying protestors isn’t the sort of thing they should be doing, but when an organization gets large and suddenly has lots of money it’s hard to know what individuals are actually doing and some of them are looney.
According to “Charity Navigator” they spend the vast majority of monies on their “programs” and have little overhead... I do not think that the analysis goes too deeply into steering money to particular lawyers or excessive fees... https://www.charitynavigator.org/index.cfm?bay=search.summary&orgid=3247
