It doesn't make any sense to me, but this Joe is obviously far more knowledgeable than me about the workings going on in F1.
With everything that is, or isn't going on at Red Bull, if Max had pulled a trick like Alonso yesterday, then the keyboard warriors would have been frothing at the mouth and caused a social media overload. The worst they could do was try and make a comment to a mechanic into a much bigger story than it was.
As much as I think Max has developed into a great driver, if he (or his father) wants to go to Mercedes, then by all means go. I'd be more than happy to have Carlos Sainz take his place.
