The Wikimedia Foundation has been involved in several lawsuits, generally regarding the content of Wikipedia. They have won some and lost others. In the United States, the Wikimedia Foundation typically wins defamation lawsuits brought against it due to protections that web platforms receive from laws like Section 230.[1][2] However, in cases in Europe and other countries, courts may rule otherwise. The Wikimedia foundation often ignores these orders, and countries cannot reach across borders to enforce any ruling.
