Business. They know that -say- 20% of their manufactured lenses are actually substandard. They know also that most consumers will not notice manufacturing defects so only a -say- fourth of the lenses will be send to service. It is a simple optimization model to balance QC and service costs + customer satisfaction effects.
However, frankly, it is not their fault. Consumers demand ever more extreme designs at very low prices. Just compare lenses made in the 70s to today's standard. Most lenses were made of metal with smooth controls ... and all with a QC sticker of them. The lenses were substantially more expensive compared to the salaries at the time. Obviously the manufacturers discovered that they can sell substantially more lenses made of cheap plastic and lesser standards. Because "we" want it that way.

Well, that's not a very good state of affairs, one out of 5 lenses shouldn't pass the QC! And that's not counting the lenses that shouldn't have been designed at all, the like of those that receive only 2 or 2.5 stars however in the "pro" segment there's seem to be quite a number of lenses which receive top mark for mechanical quality but rate quite average in optical quality, surely the designers should have been aware of this fact?
