The US Yated isn't affiliated (anymore).
In that case they would be smart if they rebranded ASAP (and foolish if they don't IMHO).
It is a known fact that the American Yated has had ZERO affiliation to the Israeli one for decades, IINM. Rebranding now would make it sound like they did have a connection until now, which IMO would be worse. The Israeli paper is not even on their radar, and for an American paper with a tremendous brand-name to start again with a new name would be a terrible idea, in my opinion.
To try to find a contrast, imagine if the original owner of the DansDeals website made headlines for being a terrible person, would Dan change the name of his website? Or would the mentality be that our respected brand has zero connection to that unremarkable bad guy and his actions have absolutely no bearing on us.
