In March 2024, Grant threatened X with a fine of up to A$782,500 for allowing Canadian activist Chris Elston (sometimes known online as Billboard Chris) to post a tweet linking to a story about the appointment of transgender activist Teddy Cook to a World Health Organization panel in which he stated: “This woman (yes, she’s female) is part of a panel of 20 ‘experts’ hired by the WHO to draft their policy on caring for ‘trans people.’ People who belong in psychiatric wards are writing the guidelines for people who belong in psychiatric wards.” Harsh words, no doubt, but clearly traditionally-protected speech. After Grant’s order, X geoblocked the post from Australia, but fought in favour of free speech until the decision was overturned in 2025.
