Avram,
I never heard of Jeffrey Sonnenfeld and his spreadsheet.
The size and amount of international companies that are partaking in this boycott and the speed it was done leads me to believe that they had good intentions and were not forced by fear of a backlash.
I agree there are late comers that are doing it for fear of backlash and it could potentially be used against any country including Israel.
But, I think that this is a clear case of an aggressor doing very bad things and it would be very hard to enact where this isn’t the case.
So far, it has not stopped Putin.
