Meta challenges Ofcom's calculations for UK online safety fees and potential fines

Reuters reports Meta's challenge opened in London's High Court on October 13. Meta argues Ofcom exceeded its powers by using broadly defined worldwide revenue, rather than UK revenue, to calculate fees and maximum potential fines under the Online Safety Act. Ofcom says worldwide revenue sets only the maximum potential penalty and any actual fine must be proportionate. Meta also disputes how Ofcom calculates fines when multiple services under one owner are jointly liable.
