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...

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!

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!

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
Or take a step towards improving your online privacy by trying out a free account at @proton.me . I'm happy to answer any questions you might have. 7/7

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
