They agreed to set up service in the falklands on the condition that they be allowed to have a monopoly. If you take that away you’re breaking a deal you made.
A bit of googling on this agreement shows that there is a 5 year notice clause, so they can just serve notice now if they want. No need to pay anyone off.
