Maybe they should avoid conversations that don't lead to accurate information instead? I can forgive lack of precision (especially when qualified), but knowingly giving another person inaccurate information is an act of sabotage.
While occaisionally talking about things that are not bullshit but sound exceedingly like it, just to keep people on their toes. The ongoing research into quantum time crystals is a particularly good topic for this.
My advice would be to simply don't hang out too much with people who believe in bullshit. People who look things up on their phones are mostly fine; they have a healthy habit.
(IME, people who complain about others having their phones out tend to be insensitive and disrespectful. The scenario I usually see is such a person happily getting their fill of social media, putting their device away, and then imposing themselves on someone else and expecting them to drop everything they were doing and engage in a conversation.)
Some conversations are held for fun, others for exchange of information. Nothing good comes from the two goals getting mixed up.
