No, you are not expected to pay $30 to anybody.
If the distribution of the money make you unhappy, just pay $30 to this guy and $30 to the other project (or $150 using a x5 ratio sugested in other comment).
Or you can use the free CLI, or a free alternative.
Even better, you can write a free clone of this app and distribute it for free. Just remember to choose the licence carefuly. You'd probably like AGPL that makes comercial use very difficult.
