Can't believe how many ungrateful persons are there. Man made a free miner (with a fee, but it's free) and you are complaining like he owns you something.
The word is "owes". Having a built-in, non-negotiable fee literally means it's
not free to use; I'm not sure why this isn't clear to you. If we are essentially paying to use the product by forfeiting a part of our proceedings to the developer, we have the right to know what we are getting. This is a business venture for its developer, and the this forum is a market they set out to conquer, so market rules apply.
