Do those laws even apply to P2P apps without central servers?
Each host will carry a legal responsibility for both what they push, and what they pull.
The law sucks but the misinformation around it is getting out of hand.
If a user is downloading a Linux image via bit torrent, or using WebRTC data channels to synchronise many clients using a p2p mechanism, what is the risk that needs age restricting?
This is what I meant, the OP is factually incorrect that just adding P2P technology to a service means it must age gate.
