If I felt like I was forming a “friendship” with one of these artificial personalities, I’d want more control - not in a maniacal way, but because I wouldn’t trust Meta (or whoever) not to say “meh, this isn’t profitable, so we’re shutting it down next month.”
We’re already far too dependent on corporations, but in most cases, they haven’t had the power to emotionally damage us in this specific way. I don’t want to give them that kind of power over me.
