Bill Clinton uses similar word games.

Anyone with decent reading skills reading that letter would note:

1.) It thanks you for sending in the tubes

2.) It says YOU reported the tubes oscillated

3.) It says the grids are damaged

4.) It says that was "apparently a result of the oscillation condition" 
that YOU reported.

There is no way for a tube manufacturer, or you, to tell if a grid 
overheated from an oscillation....or excessive drive. You have no 
way of knowing because heat damage is heat damage.

The amplifier you removed those tubes from was manufactured 
without a grid protection circuit, and early runs of that Dentron 
amplifier had NO grid meter!
