Do you have any citations for that? The answers to this Quota question: https://www.quora.com/Is-the-land-used-for-Israeli-settlemen... say all the land was bought from landlords (who of course may not have been the people living there) or was registered as public land under the Ottomans.

Which is still an unfortunate situation for the tenants, much like being evicted in San Francisco after your landlord sells your apartment to someone else, but still different from outright theft.
