It’s true for any variation of Linux. Hell, the vulnerability (Mimikatz) that was crucial in the most expensive cyber security attack in history is still there in Windows.

And for X11 to be exploited you would need to get and run malicious code in the first place. The Linux security model kicks in before you get to that point.

The security model is also very different between Linux and Windows. Linux is just inherently more secure.

Aurora gets a vote from me. I set it up for my technically repulsive father, and he gets on just fine with it.

They kind of already do. The C used by the kernel team isn’t the exact same as what everyone else uses. Mainly because of the tooling they’ve built around it. I can’t remember specifics, but the tooling in place really helps out in that department.

Also, “memory safe C” is already a proposal for the C lang project.

I’ve never used beeper, but I’ve been using Ferdium for years I have all in one app:

• WhatsApp
• Hangouts
• Discord
• Element (Matrix)
• Nextcloud Chat
• Lemmy

You mean a desktop application? If so you can use the web version, or even better, use Ferdium. It lets you connect to various messaging services and integrates them like a native desktop app.
