Alonso has given it away as well with his comment "I will drive for as long as [..] the team needs me behind the wheel."
With Max, they don't need him behind the wheel anymore.
Yes, but that's reality though (and not just for Fernando). They will kick him out when they no longer want him, even if it breaks a contract. It doesn't mean he will waive any payments that are contractually due. He might make it look voluntary.
