They are optimizing dollars extracted per customer. Either that, or they are so incompetent designing electronics they shouldn't be allowed to.
Unfortunately, electronics design does not operate outside the bounds of economics. Given a target retail price of ~$1.25/unit -- many of these bulbs are the best design possible. The existence of poor quality products does not indicate malice -- many buyers demand low end products. Cost/quality/performance is an engineering tradeoff without a "correct" answer. The answer is up to the opinion of the customer.
Buyers want cheap bulbs, they don't want crap bulbs. If that means $1.25/unit is impossible, so be it.
