> Linux on a laptop has always been unstable, insecure, hot and noisy.
Wait -- insecure? How? You mean full disk encryption? I am typing this from thinkpad with full disk encryption and SELinux enabled Fedora. Sure there are problems with Linux on laptop but even if you don't have SELinux enabled - security has never been an issue (or no worse than Windows and OSX).
What I was specifically referring to there is that Ubuntu's NetworkManager (in combination with Open VPN) had (or still has?) a DNS leak right out of the box for years.
I think you are underestimating the importance of fixing glaring security bugs ASAP when they become public knowledge instead of denying or ignoring them for years.
Also, a DNS leak is potentially much more dangerous for a minority of people than any locally exploitable bug.
