In Canada, some of the country's largest school boards are taking legal action against Snapchat, Meta and TikTok. Accusing them of promoting cyberbullying, harassment, hate speech and misinformation, the school boards say these social networks are all knowingly "harmful applications" for children. The schools concerned are seeking $4.5 billion in compensation, a change in the algorithm of the apps and a strengthened parental control system. The initiative isn’t supported by the government of Ontario province, where it originated, but its announcement quickly spread across the country.
