I see Tito Woolf is feigning indignance about the slur on his good name and has stated he is considering his legal options. However, I've carefully read everything the FIA have officially stated on the matter and its all very neutral, simply reporting a complaint has been made and they are looking at it. Not at all accusatory.
And that's Tonto's problem. He cries wolf(!) Too often and as a result no one is impressed or scared when he makes these threats because its rare he follows through on them and even rarer he succeeds.
This is all time, effort and mental capacity that would be better spent on improving the team and its cars, but he'd rather waste it talking to the media making threats no one will believe anyway. When they fail to improve relative to Red Bull next season you'll know why.
