One must also consider the cost-benefit analysis for a developer. Building a custom ROM for a Qualcomm device often involves cherry-picking commits from similar devices (a “device tree”). For the Kirin 659, there are no similar devices with open-source support. Creating a functional device tree from scratch for a tablet with no active user base is a Sisyphean task. A developer could spend 200 hours building a ROM only to find that the stylus pressure sensitivity or the five-speaker array cannot be reversed-engineered. The return on investment—measured in donations, gratitude, and personal satisfaction—is virtually zero.
