MCT are funding the first team squad, so players already signed for that squad have to be funded.
They can't pick and choose who receives wages from their donations, in the same way we can't buy a season ticket and say " I don't want X or Y player to get any of MY money"
IMO the more people who join up, the more money can be donated, therefore a better standard of player can be attracted.
Of course, if that doesn't happen, then theres always the option to resign your membership.
