I think this is a weaker example.
Judge Kaplan very likely went beyond what the law allows, in issuing the injunction against Eric Corley for even _adding a hyperlink_ to the DeCSS code on his website.
However, we don't know this for sure, because Corley did not take this to the Supreme Court. There is a chance that the SCOTUS would have accepted the case, and found that neither a hyperlink to computer source code, nor computer source code itself, constitutes "technology, product, service, device, component, or part thereof"... but at the same time, maybe they wouldn't accept it, and maybe they would but it'd cost a lot of money Corley didn't have to see the case through. So who knows? Corley seemed satisfied enough that, even though he was personally enjoined from linking to DeCSS, it nonetheless spread like wildfire all over the world, and DVDs were effectively copyable from that day forward.
But yes, obviously serious threats of violence are not protected speech.
Because then you don't really have any rights. They can't formally punish you for speech but they can punish you for breaking the same unrelated law a million other people broke without knowing and that only you were prosecuted for, "coincidentally" right after you said something they didn't like.
They can also contravene a number of other legal safeguards along the way, and disregard judges' orders.

It appears the US has elected an administration that wants to turn the country into a lawless shithole, where the powerful do whatever the fuck they want, and they deliberately fuck with laws and safeguards, and deliberately target their political enemies (e.g. student activists), to flex how powerful they are.
I kind of hate the thing where people want to make this the part that matters, because Trump is a massive outlier who doesn't care about that and says the thing he's not supposed to say.
But the people who still do the prosecution under the pretext and then don't admit to why are even worse, because they're doing the same thing and then lying about it on top of that. If all you do is punish people for not lying, that's not going to solve anything. You need to take away their ability to trump up charges against random people.
Jerry Seinfeld: You disagree?
Norm MacDonald: Yeah, I thought it was the raping.
The fact that your statement is becoming more and more true in the United States is an indictment.
Dispute that this should constitute a crime as much as you want (and please, do. Take it to court, get the laws changed, go into politics, get the US fixed, this is bullshit) but for as long as it is: being charged with a crime for "doing crime and teaching others to do the same crime" is not a first amendment violation.
The current regime (before it was a regime) got away with a lot of very bad speech because "the first amendment says all speech is allowed, no matter what" and should be made to hold everyone to the same standard they hold themselves to.

DeCSS was also available in DNS txt records for a while circa 2000.
I'll do you one better: 2600 Magazine was prohibited from saying which website hosted DRM-circumvention code:

They were legally prohibited from saying, on their own website, words like "You can get DeCSS from http://lemuria.org/~tom/DeCSS/" and nothing else. Criminalised speech.
