That's the point. They are by far the largest player in the game, and can ( and do) use their size to squash competition. You don't have to use their marketplace but as a small business you don't have many options that can compete. Hell, they're even extremely anti-competitive with their employees. Their NDAs are very restrictive and have threatened non-senior employees with them, even ones that they let go.
