This is what I found in their announcement post:

To make our app truly decentralized, dlike image sharing will soon be available on IPFS sharing will soon be available on IPFS and its code will be made open source. To ensure all this timely and properly, dlike will be getting 15% as beneficiary from all posts shared thorough the app. Out of this 15 percent, 5% will go directly to dlike.rewards and will be shared among all contributors on dlike. 9% will go to dlike to cover costs and ensure future development and 1% will be managed as dlike.fund to ensure future stability of the app.
