Audio Magic's MST treatment?

Audio Magic power conditioners and some cables are said to have this MST treatment. Does anyone know what that means?

Also they say that when you opening the power conditioners will destroy this treatment which accounts for 30% of its sound quality. Is there any truth in this, will this treatmnet be affected by the light, air? The power conditioners are not air tight and there are many Audio Magic cables that are MS treatmed which are obviously not effected by the light.

What do you think? Is this warning really true or is it just a way to prevent users opening the units and messing up with them?
