Even if it was relevant, there’s still no story here. NSA employee/contractor brought home classified files to an uncontrolled laptop lol. That’s the security leak, not some random consumer software stealing files. If you work for any security oriented company you should just assume that is going happen.
If you’re going to point fingers, point at the problem, not something you don’t understand.
Wayland has problems; it is not the problem. X needs a replacement and I strongly encourage you to research why if you don’t understand why. Wayland is relatively new, and has large shoes to fill.
It will be many years before it has matured enough to fill your and everyone else’s needs, and by then there will a new replacement for someone else to gripe about on the internet.
