Tiling windows is one of those features some power users simply love, and yes, there are ways to make it happen on KDE and GNOME with third-party apps or extensions,
For KDE Plasma, tiling is available natively via a dragging/snapping mechanism since well... basically forever. No need for any extension, special script, or extra plugin. There are stuff that improve tiling, but basic tiling functionality is there right from the start.
I work as a translator, and I usually have a virtual desktop with two windows side by side, one for the source text, other for the ongoing translation, and I use KWin's tiling mechanics that come in Plasma by default to arrange these windows.
This is just an example. TFA guy obviously is talking about something he doesn't know at all.
