The term "in-forming" refers to the act of providing information, instructing or educating someone about a particular topic. While it is important to inform others, there are certain situations where the opposite actions may be necessary. One antonym for informing is withholding information, which means keeping knowledge or facts hidden from others. Another antonym is misinforming, which involves providing incorrect or false information intentionally. In some cases, it may be appropriate to discourage or dissuade people from learning about a certain topic, which is another antonym for informing. Overall, there are many ways to oppose informing, but it is crucial to consider the context and consequences of our actions before doing so.
