All Gov does and it's not exclusive. Most Gov sues social media for unlawful content despite controlling and policing their domains.

As far as kill switches turning off content. They obviously can.

Examples

Canada Trucker Funding.

New Zealand a few times Covid, and prior terrorism.

UK does aswell.

France riots.

Europe a few places protest related.

Outside of the West frequently.

India Kashmir. Far more places.

I find it ironic there's this other backdoor into it. Because it was always there.
