This is Darwinism.
If the author has a seemingly popular and monetisable (sic) product with real users, yet has failed to achieve the state of ramen profitable, then perhaps this is fate.
Perhaps he's not able to be at the helm of a product that people would rely on in their production apps.
What if the author of this app is unable to run the product successfully and is forced to close it down. What happens to the thousands of users who have integrated his product in their stack? An expensive migration. Loss of profit for them.
Perhaps it's better to choose another product that is able to be profitable.
