In 2022, I wrote a book about the history of anonymous speech because I was worried that we eventually would lose the ability to be anonymous online. I did not predict how quickly it would happen. www.theverge.com/tech/875309/...

Will Section 230 last another 30 years?

Countries routinely use hate speech laws to punish political dissent and criticism of public officials.

The fourth edition of Cybersecurity Law will be published on Oct. 14! A new chapter on Internet of Things, along with many new sections on topics such as CIRCIA, the SEC cybersecurity regs, geofence warrants, and the impact of Van Buren on CFAA litigation.

Proposed Idaho state law could make some lies a felony crime with prison time Idaho House Speaker Mike Moyle introduced a bill to make it a felony crime to knowingly spread malicious lies about someone.

So this is concerning, especially because last year SCOTUS denied cert in a case challenging the constitutionality of criminal defamation laws. www.foxnews.com/us/proposed-...

Posting hateful speech online could lead to police raiding your home in this European country In the U.S., most of what we say online, even if it's hate filled, is protected by the First Amendment as free speech. But in Germany, prosecutors and cops police the internet.

Pretty amazing that 60 Minutes does an entire segment about Germany prosecuting people for online posts and does not include even one voice raising free speech concerns. The segment looks like it was produced by the German government. www.cbsnews.com/news/policin...

Unlike CJEU, SCOTUS is at least supposed to try to apply the First Amendment.

This opinion gives a roadmap for any future court to accept national security or privacy as a pretext for laws and actions that are intended to limit speech (as the bill’s supporters readily admitted).

Who knows if TikTok will remain back
online or who will own it in the long run. But Friday’s Supreme Court opinion will cause enduring damage to the First Amendment.

Still amazed that SCOTUS didn’t even try to hide the censorship motivation.

I do not think that tomorrow’s likely shutdown of TikTok will affect the company’s decision to seek cert. This is a liability for TikTok regardless of the app’s future in the US.

There is another important TikTok case at SCOTUS. TikTok likely will file a cert petition in Anderson v. TikTok, a Third Circuit opinion that narrowly construed Section 230. TikTok has retained Paul Clement and received an extension to file until Feb. 20.

Breyer’s latest HLR article reminds me why I am thankful for the writing styles of Kagan and Barrett.
