On alignment, good and evil are real and exist regardless of what WotC and Larian may want to claim. It's like when silly softball leagues do away with keeping score, but even little kids can and do keep score anyway. I am more than capable of keeping score even if Larian wants to paper over those real differences between good and evil.
And neutral is not good, so lumping in neutral companions with the good side doesn't fly with me. So my claim that there is no good party very much still stands.
As for the possible early reveal of who may be the last companion, my reaction is exactly the same as your reaction, @Gray Ghost. I am stunned Larian would throw out yet another utterly despicable evil companion. I revive my claim that Larian hates the idea of having to provide good characters, and throwing out recycled retreads Jaheira and Minsc as companions is their way of adding a couple of "good" companions on the cheap without having to expend (which is to say waste) any effort or resources on creating new good companions.
