Interesting.
But loss of thrust? The pitch remained stable and perfectly reasonable. Does your theory assume the engines remained at takeoff power?
There are literally only 2 ways (based on the takeoff video) that the plane, at roughly 20 degree nose-up pitch (I'm making an assumption because it looks like normal pitch), starts descending. 1) flap/slat retraction and/or 2) loss of thrust.
I think 1) has been reasonably debunked at this point.
Actually, 3) degraded thrust at some point on the takeoff roll, rotate at the last moment on the runway right into stick shaker. Airspeed decays after a brief climb, then drag takes hold.

I don't know why so many people are tripping over themselves to try to solve this investigation on this thread. The FDR and voice recorder will provide enough information. Most of the speculation coming from professional pilots is just plain embarrassing. Look at all the people who were convinced that the flaps weren't down for takeoff. Then you have people saying the RAT wasn't deployed. Then people were saying the flaps must have been retracted. All of those claims were proven wrong within a few hours. And now we have people trying to trace electrical short circuits.

I agree the gear down alone isn't the cause, but perhaps the crew was overwhelmed with all the Master Cautions? Maybe the elevator was sluggish due to the degraded control and wouldn't let them pitch down as quickly as needed? Perhaps it's safe to say their margin of error at that phase of flight was so slim to non-existent that the introduction of any number of these otherwise individually recoverable events doomed them, sadly.

since you’re playing detective, what evidence would lead to this speculation? and would that speculation be considered impugning fellow aviators as terrorists? if so, i hope we have even a shred of evidence for it.

Gear down, combined all manner of subsystem dysfunction, would not cause it descend with two engine TO thrust.
Could be, hard to judge precisely from the video. But man it sure looks like an abrupt loss of thrust in the video. And RAT wouldn't come out at or above idle.

Took the liberty of asking (AI bot of choice) to show me a picture of a 787 cockpit.
The flap lever and the gear lever aren't remotely similar in location or design.
Early days.
No competent pilot (even a baby 1000 hour pilot) would mistake the flap handle for the gear handle.
Very interested in the final report.

I think I can comfortably debunk that theory... would Air India employ a Pak? Kind of doubt it. That would be like Air France hiring a German.
