Probably because it's adequate for most people who will never put in the time an effort to exploit what an instrument may truly be capable of and that involves a lot more than tuning the focuser - like mounting the scope adequately for a start . It all comes down to $ and price point .

GSO would factor in the cost benefit of every cent that goes into these instruments and are very successful at that . They know that the small proportion of buyers who are really serious enough to find the focuser a problem will buy an after market focuser .
