They do still allow any questions from journalists and Yoshi-P often clarifies they can ask absolutely anything, even personal questions about his life. There's no question he won't answer and he's said that at media tours especially.

My guess is because they think journalists will ask well thought-out questions unlike random players. Obviously, there are many that only play the game very casually so don't ask things that people on this forum would care about, but sometimes they are more invested players or YouTubers that understand the game decently, especially during media tours, so it varies.
