To achieve this, the Xbox One was to be shipped with Kinect and was to use an always-on Internet connection as to enable numerous features, such as the ability to share games with other family members. However, when these features were first promoted, there was heavy backlash from journalists and consumers, considering these as unnecessary, privacy-invading features. Microsoft had to pull many of these features from the Xbox One prior to launch, such as eliminating the always-connected requirement and the need to use Kinect.[2] Sony took the opportunity in their PlayStation 4 marketing to play off Microsoft's missteps, such as demonstrating the simplicity of game sharing by simply passing along the physical media to another person, as well as its lower price point.[54] While Microsoft was able to course-correct the Xbox One after launch, Sony had gained enough ground with the capabilities of the PlayStation 4 along with a strong library of console-exclusive titles, and the PlayStation 4 outsold the Xbox One, 106 million units[55] to an estimated 47 million units.[56]
