We’re at a point where I’d say “why not talk about it?”
What does it do? Does it hurt the illusion that the game’s situation is all sunshine and rainbows? Reality-check : it’s not, and one morning, we’ll likely have James say “ok guys, in X amount of time, we’ll shut down the servers”
There’s almost nothing going on in Boundless aside from people saying “welp, I’m bored, bye” or people going “hey look, I made a thing, the game is not dead you guys!!!”.
There is a legitimate reason to have a talk about BG3, as explained already. You don’t want to talk about it, nobody is forcing you, so please don’t try to force people to stick their heads in the sand if they don’t want to. Not like we’re talking about it everywhere.
Unlike a lot of other games, it looks like going evil is a proper path where you gain more power the more you rely on Ilithid powers to resolve some situations. So if anything, there is re-playability, there.
