"The problem with Zionism is that it’s obscene for anyone’s status or rights in the area where they live to depend on their ethnicity or religion or where their ancestors lived." https://jacobin.com/2024/03/rights-ancestors-land-israel-palestine

With the caveat that we are speculating about someone's unspoken opinion, I think the author is more objecting to the situation where you roll up to a house and say "this is mine" on the grounds that your grandparents lived in the next village over.
In your example it is a specific property from which your direct family was forcibly evicted, and I think most Jacobin writers will have some sympathy for arguments that the descendants of the evicted have some right to compensation.
Though "grandparents parents" is a while ago, one would hope justice could be done quicker than that...
