They found its debris field. End of mystery. You have an immense overestimation of how much popular surveillance is available when unpopulated land is involved. I once had fifteen acres of undeveloped land in a rural setting, and went out to it by myself just to look around. A five-acre portion was unharvested forest. I was in the middle of that when I realized that if something happened to me, my cries for help would not be heard by any neighbor...who would never have known that I was there. That was a creepy enough realization that I immediately got out of those woods and left for home.

Anyway, all the knee-jerk conspiracy options are so much nonsense. There have been missing airplanes before. I'm just mildly surprised that so many here are acting like it is something new.
