Ok, so...
Some have said the RAT appears to have been deployed. This would suggest a hydraulic/electrical failure on the plane.
A hydraulic/electrical failure could well make it impossible to retract the gear immediately.
But, what do flaps do in the event of a major hydraulic/electrical failure? Is there a default that they revert back to?
We can, I think, rule out engine failure, at least single engine failure because the rudder is still straight on in the
Video. You can also hear the engines..

Gear unable to be retracted and flaps retracted due to no hydraulic pressure? It would certainly explain the RAT being deployed and the loss of lift.

Conceivably, it could be a double engine failure but that's very unlikely.

The chances of a double engine failure on take off are like a billion to one, and I think are certified to a million to one occurrence.
As you say they still provide power and pressure even if not running

Failing condition of switches allowing an errant object or movement to move them, a massive brain fart is possible. Followed by a WTF is going on! The apparently unopposed remedial attempt to put the switches back argues at least partially against a suicide attempt.
The other recent example is the check pilot feathering both props at Pokhara.

A suicide attempt is very unlikely, because death in that situation is far from assured.

It was a very small "window of opportunity", maybe 30 seconds longer and the plane could have been saved. Also there's no guarantee the other pilot wouldn't work to prevent it. Indeed, it was deemed that checking the safety latches on the switches was not necessary.
If a pilot were feeling suicidal it would have been so much easier for them to drive off a bridge on the way to work.
The chance of any flight crashing due to pilot suicide is 1 in 122 million. Very, very unlikely.

One thing worth mentioning is that many years ago I used to buy surplus electronics and had a switch very similar to the one used as a fuel switch. The only difference was that they one I had required to to twist and pull before you switched it, compared to the Boeing ones that you just pull before switching.
The point is it was easy to balance the switch between the "off" and "on" positions, where a simple push in either direction would then pop it into a latched position, either "off" or "on" depending which way you pushed it.
In this middle "unlatched" position I seem to remember the switch was on.

"...but the switches were found in the on position" doesn't hold water.
Just because they were found in the On position doesn't mean they were in that position when fuel to the engines failed.
One of the pilots accused the other of switching them off; human instinct would be to push them fully forward.

There are a number of factors that suggest it wasn't suicide. Until further information is released it's impossible to say

It really baffles me how the French prosecutor was able to come out
just
two days
after the Germanwings 9525 crash
and lay out the likely cause in remarkable detail \x97 even identifying it as an apparent suicide by the co‑pilot. Yet here we are with the Air India 171 crash: it took the AAIB an entire month to release a so‑called \x93preliminary\x94 report, and even then it\x92s vague, incomplete and raises more questions than it answers.
To me, this is unacceptable. If the French could piece things together and be honest about it in 48 hours, the AAIB should have been able to do better than this.

It has taken a while to get the "golden" flight recorder shipped, for instance, to recover the data.

I just checked the last one that was linked here:

I think everyone agrees that the preliminary report contains sufficient evidence to start a criminal investigation. What this thread is in two minds about is whether the outcome of a criminal investigation is a foregone conclusion.
The Air India flight reached an altitude of 625 feet in clear conditions before it stopped transmitting location data, just 50 seconds into the flight, according to Flightradar24.
That's two errors, or at least very misleading statements.
