Both technicians are correct. In most applications, the entire strut assembly does rotate when the front wheels are turned, allowing for steering movement. Additionally, a typical MacPherson strut suspension system indeed uses only one control arm and one ball joint per side, which simplifies the design and reduces weight compared to systems with multiple control arms.
