What were the initial concerns of Steve Jobs regarding the development of apps by outside developers?

Steve Jobs' approach to the App Store reflected his blend of technology and liberal arts by creating a platform that was technologically advanced, yet user-friendly and aesthetically pleasing. He initially resisted allowing outside developers to build apps due to quality concerns, but soon found a middle ground. Developers could write apps, but they had to meet Apple's strict quality standards and be sold only through the iTunes Store. This approach ensured the integrity of the user experience, while also fostering a creative and diverse app ecosystem. It was a perfect blend of technology (the platform and quality standards) and liberal arts (the creativity and diversity of apps).

The App Store had a significant impact on the tech industry. It created a new industry overnight, allowing developers to create and sell apps, thereby driving the success of Apple's devices like the iPad. However, to maintain the quality of the user experience, these apps had to meet Apple's strict quality standards and could only be sold through the iTunes Store. This model has since been adopted by other tech companies, revolutionizing the way software is distributed and consumed.
