I am saying you can't substitute any product or service. The way that a product or service is produced is relevant. I'm producing free content that's competing for your attention with National Geographic right now. If I wanted to make a beer that competed with your favorite beer it would take months (at least) and a substantial investment before the first bottle arrived at a store near you. Additionally, competition has different effects on different products. You can compete with educational content by making content that is more educational. You can also compete with it by making content that is less educational but more fun. The specifics really matter here.
