American 501c3 law is extremely lax compared to analogous structures in the EU. A number of 501c3s are run as sinecures where a board (self-selecting, so no input from the membership) just hires its friends for well-paid positions that involve little work. Because the law is so lax and permissive, making a case that a given org is not acting in the public good is extremely rare and uphill.
