Hypoxia would not account for the end of transmissions of the ADS-B, ADS-C and ACARS data. To disable these transmitters would require either consciously removing power to them (pulling the circuit breakers) or a catastrophic destruction of the aircraft at altitude. Since there is no floating debris anywhere near the point of last data transmitted then we have to fall back on choice #2: intentional disabling.

This is not the first time a pilot has planned a suicide for insurance and it may have happened here. The pilot has to disable the data transmissions and steer the aircraft to a point on the planet where it will not be found and recovered and the cockpit voice recorder recovered.

But it's all speculation at this point.

The premise of this article was that corrosion could have caused the SATCOM antenna array to disintegrate, followed by slow decompression and hypoxia.

I am not a pilot or an engineer, but when I read the article I remembered how many times I heard a flight attendant explain that in case of "sudden loss of cabin pressure" the oxygen masks would fall in front of us. Fine, but what about a slow loss of cabin pressure?
