I think I agree. That you can use it for social isolation from those in the room with you is fine, in itself. But this is akin to promoting headphones because they increase your social/situational awareness. Which is laughably false.
Such that the complaint here isn't the "by yourself, possibly in private" implications. It is the "in your home, surrounded by family" implication. You may be surrounded by them, but you are definitely isolated from them.
I do think (to whatever extent Apple is pushing it) the marketing angle that this headset will enhance in-person social interactions is pretty silly. But I also see it as inevitable PR fluff and distinct from the real compelling use cases this headset could offer.
