You don't have to be worried - or at least not more than earlier:
Certain countries always prioritized monetarian and/or non-monetarian benefits over merits in aviation. There is no difference for safety when a not able FO is promoted because of good relations, bribe money, direct pressure or when he is paying for it.
It is always advisable not to board an aircraft where these structures are prevalent, because it not only influences pilot training but also all other decisions inside of the airline.
Simple decision: avoid these airlines.
