Why not create, or donate to, a separate non-profit that focuses on improving access for poor people? Asking established entities to shift their focus to your favorite topic (or just making them, if you succeed to subvert them) feels like a sneaky way to bypass convincing people of your goals, and just redirecting funds that were meant to go elsewhere.
Because people wouldn't donate. They want to donate to Wikipedia. Wikipedia is a highly successful product. So much so that people will voluntarily pay 100x what it takes to run it. In a normal business this would be profit, and the owners would be able to pocket it.
But, Wikipedia is a non-profit, so they have to be a bit more clever in how they pocket the money. First you create a parasitic management structure. But if your administrative expenses are 80% of donations, that looks bad. So you donate to another non-profit, and that counts in financial statements as money put to work as charity. Then that non-profit can siphon off its share of administrative expenses, and repeat the cycle.
