At least Southwest took it's own initiative by adding an extra AOA indicator into 737 MAX for crew to cross-check erroneous data, but, shouldn't that be a Boeing responsibility and hence fitted to the worldwide fleet? I doubt Ethiopian purchased or insisted on these upgrades.
Is this extra a 3rd AoA or is there only 1 AoA and this IS the 2nd "comparison only" one.

They opted to have an additional sensor added as backup verification. A feature which I believe should have been installed as standard.
