My understanding that much of the legal work is donated so outreach seems like a reasonable expenditure, particularly if it increases revenues or brings in more donated legal work.
Since revenue is not profit, and most charities are non-profits anyway, more revenue does not necessarily equate to more money for betterment of the causes the charity serves.
As a complete hypothetical scenario examining two extremes which hopefully do not exist.
Charity B.A.D. could spend 100% of its revenue on seeking more donations and maintaining existing ones, leaving no resources for actually doing anything related to their cause, or distributing non monetary resources donated even. But they double revenue every year.
Charity P.O.R. Could spend 100% of its revenue, which are fixed at $10 a year, on advancing their cause.
My entire point is instead of saying 'increases revenues' you should say 'increases the money it budgets toward advancing its cause.'
The thought behind that is that they should be maximizing their effectiveness not their revenues, and so should have lots of better things to discuss.
