Very interesting, also, apparently EK's ex-MXP and ATH won't be affected.
Why would they? The issue was with the specific airports/countries of origin. Being that certain airlines flights to the US/UK invariably originate at those airports, it was taken as an issue with the airlines. But this is evidently just about the airport of origin.
So this could be a potential source of envy between passengers who travel from affected countries with a stopover in a non-affected country (such as your examples of MXP and ATH) where those that boarded at the original origin, will not be allowed a laptop (unless they obtained it at the stopover airport) and those that boarded at the stopover will be allowed.
ETA: Now if EK and EY were smart, they would create a stopover/5th Freedom flight between TLV and their US gateways.
