As with everything you read in Russia take it with a BIG pinch of salt.
Vested interests are everywhere as usual.
Who isn't to say something was not functioning at TJM that morning PREVENTING a normal de-ice op.
Remember the TU RA-85744 that (hard) landed at DME with just about 1 functional engine,-
..Blaming the fuel, the plane, anything except the crew, who eventually it turns out inadvertently turned off the fuel supply while taking off.
The blame lies at the door of a whole safety culture, or lack of it, and that goes all the way to the top through the same systemic corruption that allows people to fry in a night club for lack of fire safety.

So:-
You get on a freezing aircraft at 5am in a Russian regional airport.
Who are you to know the atmospheric conditions are ideal for icing, or your plane (
RA-
85588) is just about to catch fire?
.. or your pilot (RA-42434) is on meds that mean he gets confused at to what plane he is flying..
..or SU821 (has had a quick shot of vodka then starts swearing instead of proper CRM then turning to left when ATC ask to turn right, or missing the glide path altogether).
