LONDON, United Kingdom (AFP) — The United Kingdom (UK) government on Saturday defended a new online safety law following harsh criticism from social network X (formerly Twitter), saying it was “demonstrably false” that it “compromises free speech”.

Under the law, which took effect on July 25, online platforms must take steps to prevent children accessing harmful content such as pornography.

But X said Friday that “the act’s laudable intentions are at risk of being overshadowed by the breadth of its regulatory reach.

“Without a more balanced, collaborative approach, free speech will suffer,” added the platform, saying regulators had taken a “heavy-handed approach”.

“When lawmakers approved these measures, they made a conscientious decision to increase censorship in the name of ‘online safety’,” added the platform, owned by billionaire Elon Musk.

The government countered that it was “demonstrably false that the Online Safety Act compromises free speech.”

“As well as legal duties to keep children safe, the very same law places clear and unequivocal duties on platforms to protect freedom of expression,” said a spokesperson.

The law “does not require platforms to age gate any content other than those which present the most serious risks to children such as pornography or suicide and self-harm content,” said the government, adding “platforms have had several months to prepare”.

In the event of non-compliance, platforms are liable to fines of up to £18 million (US$24 million), or 10 per cent of their global turnover, whichever is higher.
