Well I can think of lots of reason$ to put the blame on a dead, moneyless pilot instead of a rich team owner, a skin flint airline, etc.
The only problem with that idea is that they did put the blame on "a skin flint airline." Improper training, along with lax oversight and pressure from the pilots' employers to not abort takeoffs, was cited as the main cause. That is not on the pilot, it is on the carrier. A carrier which has since been shutdown because of its poor practices found during the investigation.
Not saying the study was skewed. But it doesn't take much imagination to get to why some people would want to make sure certain findings didn't come out.
The findings painted Russian aviation in an exceptionally bad light. The investigation didn't spare the carrier as some seem to think. The whole premise behind this idea that the report could have scapegoated the aircrew in order to save Russian aviation some money is false.
