Nostr clients that don’t comply will probably get banned. I’m sure the EU will ask ISP’s what users are using Nostr, IPTV, Torrents, IPFS and Tor (and VPN’s); to add them to some “criminal” list.

Bitchat shouldn’t get affected as it doesn’t connect to the internet when in bluetooth mode. And it uses Tor so you’ll be anonymous anyway.

SO wait... all the platforms have to change their code/encryption algorithms to be in compliance?

Yep

What if they say 'no'? 'We won't do it?' Etc etc

They will probably be fined and blocked in the EU.

Furthermore, what happens to signal, proton etc? They won't comply. And those apps can't be 'shut down' either because they are widely available.

They’ll leave the EU market. (https://x.com/mer__edith/status/1796508893822238881)

Oh, and this rule doesn’t apply to politicians, only to normal people.

They want to scan all communications (even end to end encrypted) between EU citizens. Messaging platforms have to send all your messages to EU servers before encryption so they can check if you have CSAM.
