Now, from reading your comments, I'm going to assume you are in good faith, and you simply can't see what consequences they can face.

Although we can't know for sure such things without being an expert in middle-east politics, one can understand that if two groups of people have been at odds with each others for a long time, suddenly doing business with the opposite party is going to have political consequences.

E.G: assuming you are American. If you are a republican group, you can get financed by a left-leaning institution, but this will have political consequences.

There's a conflict between the settlers/gentrifiers (and their police State, military industrial complex, and security apparatus) and the rest of the population. From what i hear there is still an anti-nationalist/anti-colonization/anti-war jewish movement in Israel, what remains of a once-strong internationalist socialist/anarchist jewish movement.
