If the airlines can negotiate with one GDS to sell tickets for a $6 fee, and others stay at $12, they'll drop the others. This would make their flights not available to those using those other systems, unless they pay to subscribe to multiple GDS's - quite expensive.
In reality, once one moves, they would all have to move, which is why they are fighting it.
Not necessarily because it depends on how much money you are making from the agents/agencies that subscribe to that system. Sabre charges more of the higher fees for their system but airlines are careful about pulling out because Sabre has the market share in the US
