So here is an update on what has happened, as far as I am informed.
ricogenu (formerly known as Rico Bluestar), who was appointed as PR Lead by the GA Lead Weylin Vale a while back, has resigned from office after an altercation with Chade Dagger, the simultaneously appointed Treasurer. The two have differing versions of what actually happened, so I will leave it to them to give their versions in the comments should they wish to do so.
The following sim-owners have left Gay Archipelago (there may be more, I seem to have lost my note card on this):
Myles Capalini and - following ricogenu's resignation -
Evan Greymyst (5 sims) and
ricogenu (2 sims, co-owned with Evan Greymyst)
Harrison Constantine and
Evan Rutledge (2 sims)
