SOPA, an acronym for the Stop Online Piracy Act, was a proposed legislation in the United States that aimed to combat online piracy by giving the government more power to shut down websites that illegally used copyrighted material. Although it was highly debated and ultimately failed to pass, the word SOPA has become synonymous with online censorship and restrictions of internet freedom. Some possible synonyms for SOPA might include censorship, copyright infringement, internet regulation, online piracy, and digital rights management. These terms all represent similar concepts and concerns about the increasing regulation of the internet and the impact it has on individual freedoms and the free flow of information.
