From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Okay, well it's just the vulnerabilities you mentioned were geared towards email client issues that among other things would automatically load HTML data upon decryption. Furthermore, primary vulnerable targets were 10 year old email clients at the time that hadn't received any security updates. The SE data packet issue had been documented even in the spec since at least 2007 about its security issues and recommended rapid mitigation techniques. All in all, the EFAIL documented issues with mail client failures, not with OpenPGP itself.
Second, OpenPGP web-of-trust, or whatever you want to call it (public keyservers) is entirely optional. In fact, Proton relies heavily on this in from what I can tell actually enforces it in a more insecure way, but opting users into their internal keyserver automatically.
