The transponder was deselected, -not abruptly de-powered.
The ACARS was logged out of, which takes a number of rarely used menu selections to achieve, -it was not abruptly de-powered.
Please explain how these devices were smoothly shutdown, (with appropriate ACARS reporting) by a cb tripping or a wire loom short circuiting?
Malaysian spokeman at press confirmed these devices were de-selected.

I question the wisdom of the spokesperson. How do you know the transponder was de-selected? Because if does not reply to a request is not a valid answer. That just means that for whatever reason the transponder does not respond.
How do we know ACARS was logged out? Same as with the transponder.
If the malaysian spokesperson can tell me HOW he KNOWS that these devices were deliberately stopped from transmitting, then I may believe his statement. The statements I remember were carefully worded and left room for uncertainty.
