Conversation between @reckless.bsky.social and @butlerb.art on Decoder is one of the best tech interviews I've seen in years. Nilay is a master of pushing on executives' pressure points, and Butler is intelligent enough to answer directly (or at least to parry chivalrously). youtu.be/F3b84_tpwvg

I am so old I remember when state action in the form of a prior restraint was considered bad. And by bad, I mean like the worst thing ever. But this is prior restraint jacked up on book banning steroids mixed with horrific bigotry.

The moment a government department with “Homeland” in the name was created everyone knew that it would end up doing fascist shit.

I haven’t watched US cable news in a while and just saw 9 (9!) pharmaceutical and supplement ads, in a row, with only one exception (a magic broom thing). Is the whole TV US ad industry now “medical” products which would be illegal anywhere else?

Another reminder, though, that the Vivaldi web browser has built-in free Proton VPN access, and that that law does not apply to the Netherlands. Where I now am. As far as Bluesky is aware.

“Once people get a taste for humiliating, they will fight very hard to be able to keep doing it. Like an addiction, the competitively powerful will often put this urge above all else and behave in profoundly self-destructive ways to chase it.” www.liberalcurrents.com/the-politi/

Silicon Valley’s alliance with Donald Trump was a mask off moment and showed the world we can’t depend on US tech companies. For the past few months, I’ve been trying to get off US tech and I put together a guide so you find alternatives too. I hope you find it helpful!

"Nothing to hide" is one of the biggest lies going.
A meme showing "hard to swallow pills"; once put into a hand and zoomed into we can see the pills say "you don't have 'nothing to hide' you've just accepted surveillance culture as it is and refuse to take the simple steps that I have to push back against it."

Periodic reminder that surveillance capitalism can and is easily repurposed to facilitate tyranny, which is why it shouldn’t exist. Privacy matters.

I helped my 77-year-old father load some audiobooks on his phone about week ago. He told me today, 2 books in, that he “didn’t think anyone had ever read to him before.” I almost cried—everyone should have that.

Apparently the Paris opera house and the Millennium Falcon share schematics.
A baroque memorial to Charles Garnier at the Paris opera house that bears his name which has a floor plan of the opera house on it which strongly resembles the Millennium Falcon from Star Wars.

It's not exactly a controversial take, but privacy is both increasingly hard to come by yet also increasingly critical to well-being and safety. For the past 10 years we've been working to empower people to regain their online privacy at @proton.me 🧵 1/7

1/2 Coca-Cola gets a 2-for-1 cash grab/greenwashing award at the Olympics. They will only sell you drinks in a “reusable” plastic Coke cup. These cups cost 2 EUR, and you have to wait in line again to return them get your 2 EUR back, which nobody does. Cash grab, check. Then, the kicker…
