A post by [object Object] (@zzt@mas.to) saying: courtesy of @davidgerard@circumstances.run, Proton is now the only privacy vendor I know of that vibe codes its apps: In the single most damning thing I can say about Proton in 2025, the Proton GitHub repository has a “cursorrules” file. They’re vibe-coding their public systems. Much secure! I am once again begging anyone who will listen to get off of Proton as soon as reasonably possible, and to avoid their new (terrible) apps in any case. https://circumstances.run/@davidgerard/114961415946154957
It has a reply by the author saying: in an unsurprising update for those familiar with how Proton operates, they silently rewrote their monorepo’s history to purge .cursor and hide that they were vibe coding: https://github.com/ProtonMail/WebClients/tree/2a5e2ad4db0c84f39050bf2353c944a96d38e07f
given the utter lack of communication from Proton on this, I can only guess they’ve extracted .cursor into an external repository and continue to use it out of sight of the public
I’d bet they just added it to their global .gitignore where it should be, then removed it because they didn’t want their private dot files committed to a public repo.
I don’t think this user knows much about git works. I don’t think this is nefarious or “vibe coding” as it’s colloquially known to be. It’s a bit much to describe all LLM use blindly as vibe coding, when vibe coding usually means just blanket accepting AI content.
Pretty on point, the .gitignore in the repo has a CLAUDE.md
