Durov was held on suspicion Telegram was willingly failing to moderate its platform and allowed drug trafficking and other illegal activities to take place.
X has allegedly illegally sent data to the US in violation of GDPR and contributed to child porn distribution.
Note that both are directly related to direct violation of data safety law or association with a separate criminal activities, neither is about speech.
CSAM was the lead in the 2024 news headlines in the French prosecution of Telegram also. I didn't follow the case enough to know where they went, or what the judge thought was credible.
From a US mindset, I'd say that generation of communication, including images, would fall under speech. But then we classify it very broadly here. Arranging drug deals on a messaging app definitely falls under the concept of speech in the US as well. Heck, I've been told by FBI agents that they believe assassination markets are legal in the US - protected speech.
Obviously, assassinations themselves, not so much.
Durov wasn't arrested because of things he said or things that were said on his platform, he was arrested because he refused to cooperate in criminal investigations while he allegedly knew they were happening on a platform he manages.
If you own a bar, you know people are dealing drugs in the backroom and you refuse to assist the police, you are guilty of aiding and abetting. Well, it's the same for Durov except he apparently also helped them process the money.
I don't believe you. Not sure what you mean by "assassination markets" exactly, but "Solicitation to commit a crime of violence" and "Conspiracy to murder" are definitely crimes.
One of my portfolio companies had information about contributors to these markets — I was told by my FBI contact when I got in touch that their view was the creation of the market, the funding of the market and the descriptions were all legal — they declined to follow up.
