SCENARIO Please use the following to answer the next question:

T-Craze, a German-headquartered specialty t-shirt company, was successfully selling to large German metropolitan cities. However, after a recent merger with another German-based company that was selling to a broader European market, T-Craze revamped its marketing efforts to sell to a wider audience. These efforts included a complete redesign of its logo to reflect the recent merger, and improvements to its website meant to capture more information about visitors through the use of cookies. T-Craze also opened various office locations throughout Europe to help expand its business. While Germany continued to host T-Craze's headquarters and main product-design office, its French affiliate became responsible for all marketing and sales activities. The French affiliate recently procured the services of Right Target, a renowned marketing firm based in the Philippines, to run its latest marketing campaign. After thorough research, Right Target determined that T-Craze is most successful with customers between the ages of 18 and 22. Thus, its first campaign targeted university students in several European capitals, which yielded nearly 40% new customers for T-Craze in one quarter. Right Target also ran subsequent campaigns for T- Craze, though with much less success. The last two campaigns included a wider demographic group and resulted in countless unsubscribe requests, including a large number in Spain. In fact, the Spanish data protection authority received a complaint from Sofia, a mid-career investment banker. Sofia was upset after receiving a marketing communication even after unsubscribing from such communications from the Right Target on behalf of T-Craze. Why does the Spanish supervisory authority notify the French supervisory authority when it opens an investigation into T-Craze based on Sofia's complaint?
