Right, that is the exact line of thinking that TFA is arguing against. It's a pretty short piece as it is, but if you're looking for a TL;DR then this is as good a sentence as any:

> If a nonprofit doesn't understand better than its donors where money needs to be spent, then it's incompetent and you shouldn't be donating to it at all.

Though see TFA for some (corner-) cases where this might not apply.

Open to your thoughts on why TFA is wrong on this point - but I think you need to flesh your case out a bit more to at least address the arguments presented therein.

See Paul’s fine article. If you don’t trust the management at a nonprofit to do the right thing, then don’t give them your money.

One of the biggest challenges nonprofits face is donors who think they get to micromanage them because they give money. Any decent nonprofit has a development head who will politely but firmly tell donors to butt out, and hand them their check back if they don’t.
