It seems likely that Snoke has access to the Force, so why can’t it be assumed that he’s used the Force to get the information?

Because it’s not established that he can do things like that. Forcedunit is already a poor writing tool in situations where it’s kind of explained so no explanation at all would be nearly unforgivable. I think the best course of action is to trim the scene as much as possible while still having it be a proper scene. At least that’s what I’m doing.
