Metal contact forces are very high in the threads. Stainless is
especially prone to galling. What he is probably referring to is the
practice of putting the boat on a tack and attempting to tune the
weather rigging until it looks right under load. This can destroy a
turnbuckle.

That makes complete sense. Thanks for the explanation!

Since I have a Freedom 40/40 with a free standing carbon fiber mast, I
don't quite have these same issues.
