UK's Online Safety Act - "protect children" → age verification → digital ID for everyone
Australia's Assistance and Access Act - "stop pedophiles" → encryption backdoors

KOSA (Kids Online Safety Act) - "protect minors" → require ID verification and enable censorship
SESTA/FOSTA - "stop sex trafficking" → killed platforms that sex workers used for safety
