The FAA did put out a notice to pilots last year, I don't know if that kind of information reached Ethiopia Air though

This trope is getting old (though you might not have intentionally insinuated it) - Ethiopian Airways is not some backwater airline: it flies into the US and governed by FAA rules - so yes, that information reached Ethiopian Airways as they have a direct line of communication to the FAA.
Sorry, it wasn't a knock on Ethiopian Airways - they're a Star Alliance member, I couldn't imagine their safety standards are different from any top-tier airline.
I meant it more as in I don't know how these things propagate internationally. I couldn't find a mention if the European EASA also put out a notice, or if the FAA one gets distributed worldwide (directly to pilots? airlines? via local regulators?), or how it works. You say they get notices from the FAA since they fly to the US, does that mean e.g. all airlines that fly to Japan also get Japan air safety notices? The Japan regulator wouldn't put out their own notice on the 737?
I'm honestly trying to understand how the notices get categorized, prioritized, "deduplicated" and distributed to everyone who needs to know without overwhelming pilots with unrelated stuff.
The FAA deals with airlines, which figure out how to disseminate the information internally.

Any international organization that has to abide by laws/regulations in different jurisdictions has to be competent at this. There will be bureaucrats and infrastructure to deal with the bureaucracy: country reps, lawyers, former pilots, endless mailing lists, etc.
