I just realized I read your post too fast. Yamaha screwing Zarco... that's different. I suppose it's possible. I have a hard time imagining Hervé Poncharal putting up with that. Again, I would think Yamaha wouldn't contrive to alienate Zarco. He's a pretty valuable asset. Imagine if (for whatever reason) Rossi retires soon, or Vinales goes to Honda. They'd want loyalty from Zarco.
Thats what I was thinking Herve would lose it if swing arms started dropping.
I suspect that Herve would go apeshit if he felt that his team were being mistreated, but at the same time, this is the first year in a large number where I reckon that they are a genuine chance to win a race as well due to their riders.
But, I am being conspiratorial only as I want to think that it would not happen deliberately, and I suspect that it would not .......... but there is still a nagging itch that a cream does not fix
