ATC ordering you to divert to a rogue state, lead by a crazy dictator, risking your crew and passengers ending up as hostages, or trying to make another 3 minutes straight ahead to get out of Belarussian airspace. Either way the crew were faced with a difficult choice, and we need more details to know what choices they had in reality.
Nobody is doubting there was a MIG close at one stage, but was it an intercept or was it an escort after the RYR started it's diversion to Minsk.
Those NATO radar images would have been mighty helpful to know these details.
