No one asked you for opinion regarding a particular desktop environment
or if it's a good choice to run it or not. Those type of comment are at
least useless at most unproductive.

Yes there's people who know what GNOME does and how it's done, there's
even people who look into the source code... And people who investigated
GNOME the same way you tell this guy to investigate some actions of the
timers...

GNOME is part of the Debian distribution so this type of opinionated
answer shall not arrive. This seem as sterile discussion as talking to
some hard head politician... And it goes nowhere...
