Kareem Abdul-Jabbar, the former Los Angeles Lakers superstar, called on tech companies in a rambling essay to do more to censor celebrities, political figures and others from spreading misinformation.

Unfortunately, the long-term result may be that their professional legacies could become brief footnotes to the memory of their collection of mason jars filled with their excreted opinions."
