Played a game as a service. Spent over $2,000 in it over the course of about 4 years. The game lost its IP rights, and shut down pretty unexpectedly.
Did losing access to the game suck? Yeah. But if you take the time I spent playing the game over my account lifespan, I spent less than $1 an hour for pretty quality entertainment. It's not a fraud, and one of my cheaper hobbies.
