What I don't get is KLM? AF was avoiding Ukraine, but KLM was not...
AF and KLM were merged at the corporate level back in 2004. I'd put down AF's choice of route down to being the most direct route from CDG while KLM made the equivalent choice from AMS. Saving money on every flight is what drives routing decisions, not the remote chance that flying one route verses another will result in a black swan.
That MH elected the least costly route is an even more obvious economic decision for an airline that was already in terminal condition.
