Google aims to reach a global audience by offering free products, while Apple targets a smaller, high-income market at a high margin. For Google, tapping into a wider market makes sense, but for Apple, releasing open-source products may not be profitable if they cannot reach everyone. Apple strategically uses products like Safari and an internal search team to keep Google honest in their competition. The decline of Apple Maps compared to Google Maps is an example of the difference in approach between the two companies.
