Well Zyklon is just the German word for cyclone[0]. They's nothing inherently bad about it or the -lon suffix there.

The -lon in Nylon, however, refers to a true monstrosity and should be avoided at all costs.

I'd think https://en.wikipedia.org/wiki/Zyklon_B is more the issue.

That's what I was responding to

That particular regime appropriated and tainted a great many symbols which had long persisted with benign or positive connotations for centuries or millennia, let alone literal genocidal poison gas. 'Splainin' "just" is a heavy-lift attempt which is likely to fail for at least another few generations, if not longer.

Just like we can't use the words "agent" or "orange" now for fear of dredging up memories of other atrocities? Parts of the US may have salted the earth with propaganda, but the world kept turning.
