The bulk of it is governmental. For example, 300 javelin missiles were sent ($24M), and that's only part of one shipment of arms from the US.
I don't know how much the private funding will help. Maybe it will fill in the gaps for small items that have not been sent over.
"actively meddling in foreign conflicts"
Why is that a bad thing?
"also if our governments cared as much as keep telling us they do"
I do agree that it seems many countries are mostly just talk. It seems just sending arms shipments is all they're willing to do.
