alt Hacker NewsCould make a copypasta out of that (ha, ha.).
But like that genuinely applies to a quite large amount of things. Screenshots, screen recordings, actual regular physical cameras, unencrypted physical cables, publically-usable GPS, microphones, etc. (these are even reasonably-realistic - Wayland & phones have restrictions for screen(shots| recording), backslash on cameraful glasses, DRM, criticism of airtags, leaking typed text through the typing sounds)
Could even go broader and count in people being non-anonymous online, and people being anonymous online, as both being bad for security; were the world to have settled on one, the other would be utterly crazy.
Giving semi-arbitrary anything to LLMs should absolutely very-trivially count in this too, except that for whatever reason it's very often just not? Clipboards would get a pass just fine.
On wayland it is difficult to effectively restrict those things. You must create a security context socket and run your app in a sandbox where nothing leaks, no dbus, etc.
On kde plasma right now with all that, wl-paste still sees the clipboard at any time from an unfocused window by creating a temporary invisible xdg_toplevel window that steals focus and grabs the clipboard.
I think we need something similar to xdg-dbus-proxy to control what messages can pass over the socket.
