We've discussed Ferrari in particular leaving before but it's never been put to a poll, so...
So as the 2018 seasons kicks off it seems Liberty may begin looking at the payments system for teams and ways to make the income distribution more equal. Naturally the biggest inequality lies with the historic payments and in particular Ferrari's bonus.
Ferrari themselves have been making lots of noise lately about leaving the sport due to technical regulations, and many commentators have pointed out the payment re-negotiations coming up as an extra reason for Ferrari in particular making noises, with some saying they could quit if their extra income was taken away. Of course Williams could also potentially struggle without their historic payment also.
Formula 1 needs to increase the spectacle, but it also needs to become a fairer sport and in my opinion that means the teams have to be given a much more equal amount of money and be able to compete on the same terms -if they want to put more money into their team from outside then okay, but the sport itself shouldn't be artificially boosting teams to such an extent.
Personally I think this would be worth the potential loss of Ferrari. Even if I would hate to see them leave I think it's only due to their under-performing that the sport hasn't been harmed by more Ferrari dominance helped by this bonus budget. I would also hate it if Williams were forced out financially (although other teams do compete on less so I would think they would survive).
