Trivia: Reportedly, Barbara and Adam from the original were going to have a cameo, but it was cut, as Tim Burton doesn't believe current digital de-aging technology is believable enough.
Trivia: One of the conditions Tim Burton and Michael Keaton set for directing and appearing in the film is that they would only make it if they could use practical effects in place of CGI as much as possible, just like the original. This is why the film makes heavy use of things like old-school stop-motion animation and animatronics... CGI was only used when necessary.
Trivia: Brad Pitt, who is a producer on the film, was reportedly going to have a cameo in the afterlife waiting room as a character who was shot in the head (possibly implied to be his character Chad from "Burn After Reading"), but it was cut for one reason or another.
Answer: My guess would be that it's a combination of a few factors. The first is that she's far from the only one doing that sort of program. There are hundreds of paranormal shows, YouTube channels, etc. It would start to look very suspicious if suddenly things started happening to everyone who makes that type of content. Second, a lot of people just flat-out don't believe in things like ghosts and the afterlife. And a lot of those shows are faked, anyway. So while Lydia is earnest and honest, a lot of people won't believe it. Therefore, her show isn't exactly super risky for the afterlife. And finally, the original movie really doesn't dwell on that idea; it's basically given a few brief lines of dialogue in like one scene, and that's it. So you could also make the argument that this movie just sort of ret-conned or is ignoring that idea due to it being such a minor, unimportant element of the original.
