Huh? They disable "emissions mode" during all driving either because a) it was bad for sales - perhaps one is unable to reach race car speeds in < 10 seconds; or b) they purposely chose not to build a compliant emissions reduction system and covered it up by specifically making the cars pass only during examination.

There is no apology to be made for them. Manufacturers are required to build sustainable systems, it's not optional. Unless the initial facts turn out to be wrong, this is clearly inexcusable.

I see what part of what I said made you confused. The "unsustainable" part of what I meant was that it caused some sort of undesired effect be it affecting performance or causing accelerated wear on components that could be costly to replace under warranty or some other condition.

Either way, I agree, VW did this intentionally and there is no question as to their motives behind it. I'm sure they'll be severely punished for it.
