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.

NH state house passes "CHARLIE Act," which bans teaching, I kid you not, "critical consciousness" & "prohibited world-views," such as that queer people exist, or that slavery involved race, or, implicitly, that the Nazis murdered Jews based on identity. newhampshirebulletin.com/2026/02/19/h...

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

Aside from some payments stuff (unavoidable), one guess whose services have no AWS dependencies and were up all day today…hint is in bio.

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?

Useful post, as s longterm Protonmail and suite user, happy to see it mentioned at lot because it is good. Recently also using cryptpad instead of google docs for sensitive colabs. And of course Ecosia search for the trees! And it is reliable and good!

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!

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.

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

We don't sell ads and we don't monetize user data, and we plow all profits back into investing in new features/products/scaling. That's it. Like seemingly everyone else on the planet who sells something, we have Black Friday deals this week for new users (check them out at @proton.me ). 6/7

We believe that the best way not to leak data is not to have it, and encryption's mathematical protection is backed up on the legal front by being domiciled in Switzerland with its strong privacy laws and by the non-profit Proton Foundation owning a controlling stake in the @proton.me company. 4/7

@proton.me 's business model is very simple. People who want more features, storage space, or just want to support privacy pay us. In addition, we have a free tier for every product with the same encryption as the paid accounts. We also have family, business and organizational plans. 5/7

It started with email, and @proton.me now has a calendar, file storage, VPN, and password manager. And while nobody, including us, is perfect, we try to do things the right way by making good tradeoffs between security and usability and encrypting everything we can. 2/7

End-to-end encrypted means only the owner, and who they explicitly choose to share it with, can access data. At @proton.me , this means that if you send an email or calendar invitation or share a file, password, or collaborative document to a friend or colleague on Proton, we can't see it. 3/7

Optimist: The cup is half full Pessimist: The cup is half empty Privacy advocate: Nobody should be able to see what’s inside the cup without its explicit consent.

In never expected to have to search for “Peanut squirrel onlyfans tax fraud” to understand the 2024 election. Definitely an incognito window for that one.
