>* The website is not by a single individual with commercial interests. All revenue from the book goes to his foundation, which runs the website*

Not sure for the particulars of this case, but setting up a "foundation", "non profit (which gives one huge salaries as 'expenses')" and so on, are the oldest tricks in the book for con-men, from churches, to donations, activists, etc...

So "all money goes to the foundation" is hardly comforting (the foundation can be setup to cut them a big payslip for their consulting/services/running it, save him tax, etc, in the end make them more than they would make with a "for profit" entity).
