Of course, I only have anecdotal info on this, but I wouldn't be surprised if during the 2 months of the most serious BGS problems, they found a massive reduction in effort from daily players. When the scale of the problem became clear (including locking up some 20 systems for us in stuck conflicts) a lot of us stopped playing, or put in a lot less hours daily than before. Why work on your faction, when the result can be the opposite of intended?
Now that things are a bit better, people are picking themselves up again, but we lost (hopefully temporarily) a bunch of players, as how often can you tell someone with a hold full of explo data that as far as we know, it doesn't really do anything, or very little?
Still hoping for further stabilization so that BGS players can throw themselves into the new mechanics with more confidence. But Frontier has done significant damage to the BGS player base, that hopefully will recover. But I haven't seen this much anger, disappointment and frustration in the BGS community in years.
I guess 3.3 was a bit of an aberration in that it was an update which made this stuff worse... and was then followed by the announcement that we aren't getting further significant updates for over a year.
In that case, I guess it's reasonable to request that something gets updated - simply to get it back to the way it was - or risk losing players.
In general, though, as long as the BGS, PP, exploration, trading or whatever is ticking-over as it should be, I think the majority of players will just continue to play as much as they want to regardless of any "baubles" that we're presented with in the meantime.
Let's face it, I doubt many people are going to log in and play just so they can experience a new kind of "scenario" in TL0 Distress Call USS's or do a new kind of cargo mission that allows you to deliver your cargo to an alternate buyer.
