I don't think anyone is advocating that VCOs should produce a "perfect" sine.
Just simply a clean wave what has no audible buzz or distortion. That 's what defines a
sine - just the fundamental component. Anything else is NOT A SINE WAVE.

It seems either ignorant, sloppy or misleading for a manufacturer to intentionally make a
buzzy wave and then spec it as "sine" wave. At the very least label it something more
accurate like "buzzy wave beta testers like" ;-)

You can always start with a clean sine and add distortion as needed, but you can't go the
other way and cleanly remove the buzz to get a decent sine. I'm guessing those
rationalizing against the usefulness of clean sine waves for music synthesis have never
even used one (since nobody seems to make them anymore...).
