Not at all.
I do think FD have definitely confused the issue for players, as a byproduct of their original naivety that players would care about superpower allegience before factional allegience. I think their lack of firm language and evasiveness around the general BGS has also contributed to a substantial amount of further confusion. And don't forget the lunacy of PMFs, which FD thought was just giving players the chance to add a lick of flavour to the galaxy, not a flag to rally behind.
But none of the gradual release of information is necessarily outlandish or incongruent to the BGS being that background flavour, and facilitating indirect interaction between players.
It's still to this day not clear exactly what contributes to war & election success. Sure, the big ticket items are known. But it's only natural for a player to see a war, and want to help one side win... or see an economic boom and take advantage of it for profit.... or how to help an outbreak... and as you get more understanding, you'll notice you can spin profit in medicines during outbreak, so you start to want to increase the chances of that state occurring.
Of course, some of the mechanisms there aren't straightforward, and i think that's a failing of the BGS, but i digress... more information about how the bgs reacts fits right in with an awareness of how your actions can affect the game world.
And sure, that can be seen through the lens of encouraging direct interactions.... but that doesn't mean it's no longer just background flair either. I think what FD has done is increased information for players as much as they can while both staying in the remit of the BGS being the backdrop we play against... but given the ways people play, there is always overlap with that competitive aspect.
Some firm, direct language would clear that up, but when players can't even understand that Squadron allegience does not mean you "own" a faction... i think FD is quite aware that such language would just alienate some players.
So, no, i don't think FD needs to keep a tight lid on the black box even if this is just background flair, if only so players can have more meaningful interactions with it. There will be overlaps with group vs group activity, but that's secondary in nature. But i do agree it's become confused as time goes on.
