Sorry for exposing the internals of running a non-profit. But I think transparency is especially important here. :)
I don't know why you feel sorry. Transparency is important for non-profit, at least for most I guess.
Non-profit is just a tax and legal designation. After any necessary compliance with that, the degree of transparency, salaries paid, competitiveness, degree of being closely held, and indeed all other things... is completely variable.
