I tend to agree with RetiredBA/BY
MCAS or not Airmanship was sadly lacking in these accidents.
On the last accident ET out of Addis. Short trip, light aircraft, erroneous Stick Shaker on take off. This appears to have distracted the crew so much they forgot the basics. Airspeed, pitch attitude etc.etc. So much so, they forgot to reduce power from TOGA, the aircraft remained with full power set, for the whole short time airborne.
