What’s the difference for a real user between using X11 or Wayland nowdays? I haven’t found anything useful on the internet, so I’m asking you. Internet articles on the topic (and about WMs too) seem to be advertising slop since they explain anything but the real things. Also, if anyone used the XLibre fork, I would love to hear about your experience with it.
Security
When you use X11, you allow any program running on your computer to access anything on your screen and clipboard, collect your keystrokes and type. It’s trivial to implement a keylogger, for example. Do not buy into the whole “no viruses on Linux” thing, it’s not true and likely to become even less and less true, as desktop Linux is becoming popular.
Wayland at least tries to put some barriers in place against this.
