Less than 1% of Palestinians are Jews. 93% Muslim. 6% Christian. The homes in question were stolen in previous centuries from Jews and the society was in shambles. The people moved were half a million at most. Gaza and the West Bank are quite nice regions containing beaches and workable land. They had no representative government and were subject to the fallout of a war and a collapsed government. Given the circumstances, they made out with more than they were owed.

Israel funding Hammas is a common misconception used as propaganda. It made concessions to try and help it reform, such as work visas. It was trying to keep the peace. Sure, there are factions in the Israel government that want to use Hamas as a wedge between a unified Palestine, but saying that it was straight up getting funding is skipping some nuance.
