LONDON: Meta, TikTok and X on ‌Friday ​lost a legal challenge against British regulator Ofcom over the amount of information it is demanding they provide under Britain's nascent online safety regime.

The ⁠challenge is one of the first in relation to the 2023 Online Safety Act, which sets tougher ‌standards for platforms such as TikTok, X and Meta's Facebook and Instagram ‌with the aim to protect children from ‌harmful and illegal content.

Ofcom has ‌been gradually implementing ‌the regime, with its requirements backed up by ​the threat ‌of fines ​of up to ⁠10% of a company's global turnover for the most serious breaches.

In February, it ​issued ⁠information ⁠notices requesting detailed content moderation metrics from the tech companies, including data on how ⁠many posts were removed or had visibility restricted, and how many users were exposed to harmful content.

Meta, TikTok and X argued the ‌notices create unprecedented regulatory burdens, but their case was ​rejected by London's High Court.

None of the companies, nor Ofcom, immediately responded to requests for comment.
