What is a common context in which 'decry' may be used?

The term 'decry' is most commonly used in the context of expressing strong disapproval or condemnation of something. When someone decries an issue, they are openly criticizing or denouncing it, often to bring attention to a problem and to advocate for change. This usage aligns with the idea of protesting, as it involves public expression against something that is considered wrong or harmful.

In contrast, promoting a product, supporting a cause, or stating facts generally involve positive or neutral expressions rather than condemnation. Promoting a product focuses on highlighting its benefits, supporting a cause often involves advocacy or encouragement rather than criticism, and stating facts is about providing information without necessarily conveying any value judgments.
