Are you talking about the AI content or something else? Because using it to come up with ideas is honestly not a problem in my opinion. If someone suggests something in conversation it's not stealing to do it, especially if it's vague like the AI prompts usually are
He didn't lie, trick anyone, or steal anything. I can see why you'd dislike it, but people voluntarily giving up their own labor is not something I get worked up over, especially when we don't know if he even used it.
Tom Scott asks viewers if they know of any interesting places for him to go visit, since his videos are about interesting places and things. Nothing crazy, essentially like a music critic asking if any fans want an album reviewed. Which many will actually charge for via Patreon. The fan who requests the video didn't make the video. Many of his videos contain too much personal experience to be plagarised or anything of the sort, it's obvious that Tom at least has a major role in writing the videos.
Plus, he pays people to subtitle and revoice his videos in a ton of different languages. I think it's odd to assume that he doesn't pay people that help with writing when it's been shown that he pays people for services that Google literally asks fans to do for free.
Calling it "wanting to use ideas for free" is technically accurate but wrong. Asking fans what videos they want to see typically isn't seen as a bad thing. Dude traveled the globe for a decade looking for random cool shit and local town lores, of course he's asking his giant community for leads on weird local things.
I dont know tbh, he kind of shut down any questions in the comments, and I unsubbed shortly after. Plus his little fans got quite abusive when people did ask.
