From speaking to someone who used to work at Toro Rosso and still has connections there, apparently Max's race engineer and another engineer got rather publicly (in the office) sacked after Max got pulled up to Red Bull. They were seen to be being disingenuous towards the team (putting Max's success above the team) with a view to follow Max as Rocky has done with Vettel (he was Vettel's Torro Rosso engineer when he won his first race and is still with him at Ferrari).
