As for BG3 and its characters - they now belong to WOTC and I think they understand how important they are for the community. I trust that they'll be treated with respect.
No, you misunderstand. Think of it as like the tone of Thor (in God of War Ragnarok) saying "you look like a calm and reasonable person. Are you? A calm and reasonable person?"
It's a veiled threat; they're saying "WOTC will face massive backlash if they don't treat our creation with respect".
