Without wanting to offend Synn, someone who has improved the forum significantly and whom I value and appreciate as a poster, I have wondered more whether it was the other way around, and that Valentino possibly might have chosen to stayi at Ducati at least partly to thwart MM/keep him off a current Ducati. I thought a GP25 at Gresini was a good option for MM (and Gresini) but likely an option which VR46 could thwart.
This is all speculation, but it is crazy if he is going to carry this grudge for the rest of his life, he never needed the 8th/10th title to surpass Ago, everyone knew he had already proved himself to be superior, and MM obviously didn’t take the 2015 title away from him, Jorge Lorenzo who rather wanted a 3rd title himself did.
