Markle and her husband Prince Harry, 41, have repeatedly spoken about their concerns surrounding online safety and the impact social media can have on children’s mental health.
The duke did not accompany Markle to Geneva but has previously supported Archewell campaigns focused on digital wellbeing and cyberbullying.
The duchess’ appearance in Geneva forms part of the Sussexes’ increasingly prominent international advocacy work since stepping back from royal duties in 2020 and relocating to California.
Through Archewell, Meghan and Harry have focused heavily on issues including online safety, misinformation, mental health, and digital responsibility.
The debate surrounding Markle’s latest post also reflects the continuing tension around how the Sussexes balance privacy with public visibility.
While the couple have fiercely criticized media intrusion into their family life, they have also periodically shared curated photographs and videos featuring Archie, seven, and Lilibet across documentaries, interviews and social media campaigns.
