What is the term for a refusal to buy or use goods from companies that support an opposing cause?

The term that refers to a refusal to buy or use goods from companies that support an opposing cause is "boycott." This practice is often employed as a form of protest against companies or governments that are perceived to be acting unjustly or unethically. By not purchasing goods or services from these entities, individuals and groups aim to exert economic pressure, thereby compelling them to change their policies or behaviors.

Boycotts have been historically significant in various social movements, including the Civil Rights Movement and anti-apartheid efforts, where consumers rallied together to influence change by choosing not to support organizations affiliated with oppressive practices. This strategy is typically organized and can take many forms, including targeted campaigns against specific brands or widespread movements involving multiple products.

In contrast, other options refer to different forms of actions: a strike involves workers refusing to work to promote their demands, a protest is a public demonstration for a particular cause, and a sanction often refers to penalties imposed by countries or international bodies on nations to enforce international laws or norms.
