GOLD hasn't disbanded, they just had some dude manipulating their newer members into getting him elected as their leader. I guess the older members didn't care for it so they planned to ignore him during his time of office. The guy didn't like it and figured he could disband the alliance. It's like... If one guy tried to abandon the alliance and shut it down, but that alliance has tons of members who don't want it to, even that toolbox is the leader, if enough core guys get together they can simply rebuild the alliance.
Although it did set GOLD back a peg in the PR department, I don't think it'll matter very much in the long run. They're good guys for the most part.
