MEXICO CITY (Reuters) – Mexican President Andrés Manuel López Obrador stepped up his criticism of restrictions on freedom of expression on Wednesday following moves by major social media companies to suspend access to the president of the United States, Donald Trump, to his platforms. Without mentioning Trump by name, López Obrador said it was not correct for private companies to appoint themselves arbitrators of what was acceptable for world consumption. “I don’t know if you have noticed that since these decisions were made, the Statue of Liberty in New York is turning green with anger, because it does not want to become an empty symbol,” López Obrador told reporters at a periodic press conference. “What we want in Mexico is that freedoms are guaranteed,” he said. “Zero censorship. Prohibition prohibited.” Facebook (NASDAQ :), Twitter and YouTube are among the platforms that, at least temporarily, have cut Trump due to concerns that he could spark violent unrest following the assault on the US Capitol building by hundreds of his supporters last week. López Obrador, a militant leftist, led massive protests in Mexico in 2006 alleging that the presidency had been stolen from him. He cried again when he was defeated in 2012, finally winning the job in an overwhelming fashion six years later. As a critic of Trump while in opposition, López Obrador as president has regularly paid tribute to the American leader, who is disliked in Mexico for his insults against migrants and threats to inflict economic pain on the country. López Obrador made mention of Twitter, which has permanently suspended Trump’s account, and Facebook. He is not the only global leader who has expressed concern about the actions taken by social media companies. German Chancellor Angela Merkel’s spokesperson said this week that she found the permanent suspension of Trump’s access to Twitter problematic. López Obrador also expressed concern about an “invasion of privacy” by companies, giving as an example what smartphones are capable of learning about people’s lives and personal tastes.
