Businesses do not care about people, I can pretty much guarantee those were added in order to waive liability. Example: person commits suicide because they see it in a show, family sues show company because that is linked to the person’s suicide, arguing the show encouraged the person to do it.
Would that hold up in court? I don’t know, probably not, but the company doesn’t want to deal with that. So they add a warning instead so they can just point to that and it gets thrown out immediately.
