1. They get tax money to subsidize their infrastructure costs.<p>2. They sell the utility their infrastructure provides.<p>3. They sell the ability for content creators to create content, that they again sell to their users.<p>They get paid to build a distribution channel, and then charge people the ability to create and distribute content through their stream, then charge for the content.
