boycott
Synonym discussion
Sense: verb/1
For this sense, boycott usually means refusing to buy from, join, or deal with someone as a public protest. Avoid is much broader and often personal: you may avoid a shop because it is expensive, with no wish to send a message. Shun is closer, but it often stresses social rejection rather than organized pressure for change. Blacklist is more formal and usually involves putting a person or company on a list that blocks work or contact. Ban is different because it comes from authority: a school can ban an app, but users can boycott it. Students may boycott a lecture to protest the speaker, while a customer may simply avoid a cafe because the coffee is bad.

Etymology
Boycott comes from the surname of Charles Cunningham Boycott, an English land agent in Ireland. In 1880, local people stopped working for him, trading with him, and speaking to him during a protest about rents and land rights. His name quickly became a verb for cutting off support or business as a way to force change.
