Reddit has launched a High Court challenge against Australia's new Social Media Age Law, which bans users under 16 from social media platforms and imposes fines of up to A$49.5 million for non-compliance.Prime Minister Anthony Albanese's government defends the measure as crucial for protecting young Australians from cyberbullying, grooming, and harmful content.Reddit argues the law is unconstitutional, infringing on implied freedom of political communication and speech, while Sweden considers a similar approach despite warnings about potential circumvention.
