I've done so dozens of times. Never had this problem.

A more accurate title for this email therefore might have been: How to write a Gnome/KDE virus in 5 easy steps. But since Gnome and KDE are predominantly used under Linux, I feel that a virus based on those vulnerabilities would impact Linux users the most. Thus, the chosen title remains valid.
Calling the method a Linux virus just because it would affect a large number of Linux installations is entirely invalid and irresponsible.
With the misinformation already in existence, coupled with some companies active campaigns to create further misconceptions, the last thing Linux needs is an article implying that it contains a vulnerability when it does not.
The problem begins and ends with both desktops as should be the solution.
Sorry, but you don't get to extend the issue to Linux just because its a very large percentage of the KDE/Gnome users and the title sounds more dramatic when you say Linux instead of KDE/Gnome.
The best code editor I have ever used. I wish I still had the original disks when it was written and published by Underware.
