Agreed. An example of this would be the mention of rival engine Unity in part 6:
"But Unity, the most widely deployed engine for small/mobile games, deploys a flat “per seat” fee for its engine. As a result, for users with a Unity Pro license, even a game with $1,000 in revenue would generate revenue for the company."
This is inacurrate, in fact Unity previously waived these fees for the first few thousand dollars of revenue earned, and with their current plan it looks like licencing is free of charge for dev generating less than 100k/year.
