It doesn’t actually give a reason. It hasn’t created an impact? It’s obviously done something better than nothing

That’s like me donating a dollar to a charity and saying “this hasn’t done as much as I thought. Might as well not donate anything”. At least based on the answer they’re giving.

It sounds like with so many different little places to give to, a large portion of them don’t end up getting much because people choose other things.  However, there’s still paperwork involved with interacting with all these different charities, tax stuff, etc., and if I had to guess, for a lot of those little-paid charities, It’s more work than it’s worth, and they could give a lot more to a handful of places by saving on manpower and resources by not fiddling around with literally a million different organizations.

That’s what I got out of them spreading themselves too thin.  A billionaire could change the world, but spread that money evenly and everyone gets less than 15 cents… the world isn’t changing if that happened.  The entire point of a charity is to get lots of people to give a little to make a lot to do something big… so Amazon giving a little bit to a million places is sorta the opposite of pooling together money to make change happen.
