Firstly condolences to those who have lost loved ones in a part of the world where this can mean a great deal of additional hardships.
Pprune falling into a few of it's regular traps with debates on whether it's AMSL or GPS altitude and so on. With the usual major provisos about FR24 data (it does show the aircraft airborne at 93kts), it is reasonably clear that it never achieved a normal climb rate for more than a few seconds and therefore it is obvious it never climbed much higher than the surrounding terrain. I'm not current on B737 MAX but my understanding is that MCAS would not be active with flaps out as they must have been at that stage. It did however accelerate in forward speed considerably so it was not short of power.
Bear in mind there is a new reformist PM running Ethiopia who is of a different tribe to the previous power holders and that the flight was to Kenya which has, along with Ethiopia had some security issues with Somalian groups. Nonetheless the profile tends to indicate the cause may lie in the territory of spatial disorientation, configuration, mishandling or technical failure. Not casting unfair aspertions but that is often where the cause lies.
RIP
