I get a feeling a lot of the people criticizing him haven't watched the channel. I've seen about 50 videos, and honestly cried with a lot of them. They've made me reevaluate my own life and reconsider how hard life is for others. It has also nudged me to donate time and money to particular communities that struck a chord with me.
I think it's great content.
Sounds like the kind of thing someone would be transparent about. As far as I know, there is no evidence that any of his claims are true. They could be, but he has a huge monetary incentive to lie.
Also, his vague language is a bit of a red flag. I put money back into my community when I spend it. But I call that shopping, not altruism.
I have seen him let the Whittaker family buy trolleys full of stuff from Walmart for their house. I have seen that prostitute (Angel maybe?) interviewed a second time after he paid for her rent and gave her money multiple times after the first video and it turned out she was just giving it to her pimp (and she doesn't refute any of this on camera).
So does he deserve total faith based trust, no, but it's easy to see enough of his videos where they are clearly benefiting from the funds and that's probably enough for many of us to say it's net positive.
Perhaps you should spend 5 minutes researching what you know nothing about before you opine about it. In particular, there is a poor, inbred family in Appalachia that he has visited (and befriended) several times over the years and that the funds he raised have helped them move from their dilapidated trailer into an actual house, among other things.
