My educated guess would be something along these two threads:
* Higher data density => tighter tolerance => same physical degradation is more catastrophic (DVD ~7x density of CD, BD-R ~20/10/5x DVD density = up to 140x CD density)
* Produced later and therefore like all consumer goods, less regard for durability and more regard for absolute cost optimization
