MCAS is operational with flaps up. Most (if not all) airlines do not start retracting flaps till 3000’ AFE. According to reports, Ethiopian never achieved anything higher than about a 1,000’ (not even close to 3k).
Most opinions on here are probably from media types baiting for info so they can self profess themselves for the cameras. Give it a rest till something concrete comes out from the FDR/CVR etc investigations.
