The funding was to buy guns, to buy UAVs, to train snipers and gunners. Not sure how any of those are going to help kids get away from explosions.
Facts are:
1. Patreon is a private company.
2. I don't think their policy around the whole funding military stuff has changed recently. If they changed the policy when this happened or to specifically target this. That would be quite terrible.
3. The page was against the rules of the company. It's perfectly reasonable for a company to remove a page against its rules. It's technically on the organizers, why did they create a page on a website that explicitly does not allow military funding.
I am guessing we wouldn't be this supportive of a private company funding the Iraqi Army fighting against the illegal occupation of their nation by the US.
Germany disagrees with you as a country that does not ship military equipment to war zones.
At this moment war is happening mostly outside of the cities. Soon it will be there and urban warfare is cruel. 100BTC or Patreon donations will not stop it. The best you can do for those children is to help them to evacuate to Europe, to get proper accommodation, medical help and education. Pointing towards charities which do that is morally right thing.
