She has not been jailed and we don't know what she posted.

Obviously there is no ground to ban every news but I agree something should be done about politicians and media spurring hate.

What would a blockchain provide here?

A fake news meant to stir up racial hatred.

So she has been arrested, not jailed. We don't know much about this specific case yet but this has nothing to do with a rant, like you said.

Can you give an exemple of such case in the recent events in the UK?

Yes, to create an account, but not to contact someone. You have an habit of being off the mark.

Also there is a difference between giving your phone number to some service and giving it to some random on the internet.

You don't need the phone number to contact someone with Signal.

Metadata is data. While we can be pretty sure that message contents are secure we have to rely on trust for the metadata.

I use Signal and trust it way more than most other apps but still, one have to be careful, a state actor could still find ways.

Are people really jailed for rants in the UK? I've only seen stories of actual call to violence.

The Russian government has also allegedly begun preparations to block the WhatsApp messaging app.

Couldn't they block them too? Monitor the domains people connect to, check if it's a Matrix server and block it if it is.

The whole point of not being federated is not to call the other servers. I don't run a server but I hope it's not calling home if specifically configured to not be federated.
