And from a pure privacy perspective, the problem there is that once you’ve demanded every encrypted app add a scanning component, then changing what you scan for is just a software update to be agreed upon quietly in some committee down the line.

So what worries me come December is that we see a bunch of “moderated” proposals that preserve this central architectural change, but just use it for slightly less. That’s not going to save anyone.

The problem with this idea is that most “moderated” versions don’t solve the central problem: you’re changing private, encrypted messengers to have a component that scans the plaintext of the message. This is what potential makes your messages vulnerable to theft.

Germany has agreed to stop ChatControl for now, due to huge amounts of public pressure. Good job! The bad news is that it could come back as soon as December, and the German government has interpreted the feedback as a need to “moderate” the proposal.

I’m sure we’re going to get details that will clear this all up so it makes sense.

Company was valued at over $225m before the 2020 election. It received a $787m payment from Fox News, which presumably didn’t stay inside the company but maybe also didn’t hurt the valuation. This seems like a pricy purchase for a guy whose previous company is so small.

Huh, ID checks not such a great idea

The Discord Hack is Every Users’ Worst Nightmare
A hack impacting Discord’s age verification process shows in stark terms the risk of tech companies collecting users’ ID documents. Now the hackers are posting peoples’ IDs and other sensitive informa...

David Simon, creator of ‘The Wire’, being interviewed by Ari Shapiro (NPR)
SHAPIRO: OK, so you've spent your career creating television without Al, and I could imagine today you thinking, boy, I wish I had had that tool to solve those thorny problems...
SIMON: What?
SHAPIRO: ...Or saying...
SIMON: You imagine that?
SHAPIRO: ...Boy, if that had existed, it would have screwed me over.
SIMON: I don't think Al can remotely challenge what writers do at a fundamentally creative level.
SHAPIRO: But if you're trying to transition from scene five to scene six, and you're stuck with that transition, you could imagine plugging that portion of the script into an Al and say, give me 10 ideas for how to transition this.
SIMON: I'd rather put a gun in my mouth.

We're now finding out that as many as 70,000 people had their government IDs provided to prove their ages leaked by Discord. Like I wrote last week, this is an inherent risk (and made greater by a rushed process) of getting platforms to do age checks
Discord says 70,000 users may have had their government IDs leaked in breach
The ID pics had been submitted as part of age-related appeals.

Bray is a historian at Rutgers who received death threats after landing on Turning Points USA's Professor Watchlist. As a result, he announced he was moving to Europe. And then this happened.

This kind of harassment and abuse of scholars is Charlie Kirk's legacy and it's only getting worse.

“Someone” cancelled my family’s flight out of the country at the last second.

We got our boarding passes. We checked our bags. Went through security. Then at our gate our reservation ‘disappeared.’

I hear that the EU ChatControl situation is going better today. I cannot believe how close the EU has gotten to passing this crazy regulation.

If AI became quietly superintelligent in 2018 and began reorganizing our world to its purposes, would that look very different than what’s happening today?

Anything is possible to pull off if you’re willing to force someone to redesign their app, and you’re not concerned about security. Just force people to upload the texts to a server before they even get encrypted.

It's too long a story to explain how I know this, but I once found out that the FBI made challenge coins about how they tried to force Apple to break iPhone encryption. Challenge coins celebrating shitty behavior is deeply a part of FBI culture.

The challenge coins being handed out by @FBIDirectorKash. Seems someone put a lot of thought into this.

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...
