I assume most if not all of the other secessionist system are also back to fed control.
So maybe Hudson is tanking in the PP thing, but BGS wise, it seems it's back to normal.
It is sending a very conflicted message.
It's a mixed bag. I was part of an attempt to support those factions, but we stopped after a few months with nothing from Frontier, under the reasoning of "if the Federation playerbase want their civil rights they can bloody well put in the work themselves".
At our peak, the secessionist factions had gained quite a few systems among themselves, for a decent net positive in all three waves-. One of our particular goals was to help the third-wave factions, who started with no systems controlled, figuring that'd be the most notable. We didn't want to mess with some of the factions, however, as they were either detrimental to PMFs or various Powerplay spheres (including Winters,
hilariously, which nixed Azaladshu).
Since we stopped, many systems have been lost. I haven't been monitoring for coordinated activity, but a cursory check doesn't look like it. Usually it's random PMFs moving in.
Anyway, actual point: the first wave of factions to leave are at -3 systems (-38%), the second wave at -7 (-21%), and the third wave is +5 systems (starting from none, so plus infinity). The third wave is still doing great, with every faction that could gain a system without trampling a PMF having done so. But we probably should have publicised it more when all three were doing well.
