I'm sure most successful multiplayer games get pushed a lot by streamers so that they make even more money (games like Among Us would never be as big otherwise) and I guess smaller singleplayer games get a push as well. Not sure about big AAA singleplayer experiences but I guess they won't really suffer from that
Same with music. People don't stop to buy a song or listen to it with their Spotify account just because they heard that in a stream. No, many will search for that song only because they heard it in a stream.
The only things which I see as big problem is music on Youtube if it isn't from the official channel. Or if streamers would just stream a movie and let people watch that movie for free.
