While I’m not a fan of Big tech, but this surely is nonsense. Are they saying there are more vibrations than, say, living in New York? Near those train lines and billions of cars (and there are probably data centers there too).

In which way is it untrusted? If you use CachyOS, you use their binaries, that could contain anything at all inside of them. Do you draw the line at a shelll script you can read yourself?

I don’t really see how GNOME is any more keyboard focused than, say, KDE. If anything, other DEs give you much more freedom for a keyboard workflow.
