Palestine was historically Canaanite, long before Judaism was even invented in the 1200s BCE. Yes, the Israelites, along with the Egyptians, the Assyrians, the Babylonians, the Persians, the Ptolemies and the Seleucids, the Romans, the Byzantines, the Samaritans, the Arab Caliphates, the Seljuks, the Ayyubids, the Mamluks, the Ottomans and others came to occupy the land at different times -- but before these illegal conquests, the indigenous people of the land were solidly of Canaanite origin, heritage and culture. Considering the land as belonging to a different people doesn’t make sense to me.

So I am not sure what is controversial or disgusting.

Microsoft's providing matching donations to groups seeking to maintain Israel's illegal settlements in the West Bank (including at least one military academy), under the guise of supporting "charitable" donations -- is what some people find controversial and disgusting.
