While this is true it's still good to add nuance.
There is a difference between judiciary and intelligence context in these kind of things, if you use a tool in a judiciary context you burn it (as with the FBI malware on Playpen). So it's probably better to keep it low, even avoid to use some of the information gathered, so you keep the intelligence source.
I'm not saying that's what's going on, just that this is not an absolute proof.
How does it compare to tridactyl?
You are right that there are underlying causes that needs to be addressed. That's why it spread so much and so fast. But that doesn't make racially motivated fake news OK.
But this seems easy to automatically block, no? If a client is querying an unknown domain check for some Matrix related data in /.well-known/ and add it to the block list if there is. And since the servers are publicly advertising the port used you just need to periodically check the list of known matrix domains you are creating in the first step.
Russia is already doing DPI and blocking ESNI so that seems easy. A more widespread usage of ECH would help everyone, as is Signal advocating, but that's not the case yet.
But no one is saying that a single tweet started all this.
But what's the link with the arrested woman?
I did not know about Rotherham, what's the link between the two?
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.
That's not fair, I want to downvote you now.
Yes but that's not the same. Because of Chrome limitation it can't update it's blocklist directly. You have to update the whole extension to update the blocklist and that goes through Google validation in the Chrome store. It adds delay and Google could even refuse some updates. The blocklist is also shorter because not all filter rules are supported.
