When there is a competing community goal, such as the current Winters vs Hudson CG, you should only be able to sign up for one of them.
These kinds of CG should be there to drive the story, and commanders should choose which side to take based on the story outcome and not the reward.
By locking out the competing CG when you have signed up for one of them, it forces the commanders to choose a side and not to contriubte to both.
Complemetary CGs, such as the trade & bounty CGs are fine to contribute to both, as they are for the same side and the same goal.
Maybe you could even hide any rewards over and above the credits, to prevent reward bias: e.g. for the current CG "a double engineered scanner" will be placed in storage - this could then have been a Kill Warrent Scanner, Wake Scanner (which would have been better than the Electroinc Countermeasure) or a Manifest Scanner; but you wouldn't know which one until completion.
