I told you so, 2016 edition!
For those not understanding the reference. Whenever GNOME, Plasma or Unity have a vulnerability in their lock screen implementation the author of xscreensaver does a blog post called "I told you so" (e.g. https://www.jwz.org/blog/2015/04/i-told-you-so-again/
). Basically saying that everybody except him is not able to implement a secure lock screen. And here we are: a vulnerability in xscreensaver. So finally I can do: I told you so!
