The idea that KDE is not objectively more configurable, in every way, than Windows, is lunacy.
However, GNOME is completely the opposite; doing anything differently requires installing special extensions, which break every time an update happens. The devs do not want you changing it from their One True Vision for how a desktop should work (which, apparently, is almost identical to a tablet).
People who aren't Linux experts or long-time users may not even know about KDE, Xfce, etc., and just think that GNOME is the only way to use Linux. Most distros push it very strongly, and even in corporate environments it's pushed hard. My company uses Linux, but the IT department only supports GNOME; luckily I'm able to install KDE but I'm basically a reneage by doing so.
So if we're comparing Windows (which has only one DE, the Windows one), to GNOME (which for many users is synonymous with Linux), I'd say he's right: Windows is much more configurable and easy to customize.
Why the Linux world has gone this way, I honestly have no idea. It almost seems like a conspiracy.
