Global tech giants including Google, Facebook and Twitter on Thursday expressed concern about a possible Singapore plan to bring in a new law to tackle the threat of fake news, saying sufficient rules are already in place. In a submission given to the committee before testifying, Alvin Tan, Facebook’s head of public policy in Southeast Asia, said: “We do not believe that legislation is the best approach to addressing the issue. Singapore already has a variety of existing laws and regulations which address hate speech, defamation and the spreading of false news.” True news tends to be met with sadness, joy, anticipation and trust. Humans are more likely than automated processes to be responsible for the spread of fake news, according to a recent study by Massachusetts Institute of Technology.
