Monetized is an adjective that implies earning money from something. Its antonyms, on the other hand, are words that indicate the opposite of monetizing. Words such as "non-commercial," "volunteer," "charitable," "non-profit," "free," or "unpaid" are some antonyms for monetized. These words suggest that when something is not monetized, it is not intended to generate income, but rather to serve a different purpose. For example, a nonprofit organization is not created to make money but to help the community. Similarly, a volunteer project is not a means for earning but an act of service. Overall, monetized is the opposite of not-for-profit activities.
