A huge strobing light in the shape of an “X” that was placed atop the San Francisco headquarters of the company formerly known as Twitter was taken down Monday following a complaint filed by the city, according to local reports. The company, recently renamed “X” by owner Elon Musk, refused entry to officials twice over the weekend after they were dispatched to investigate, resulting in a “notice of violation” for placing the installation without obtaining a proper permit from the city. A notice of violation can result in a number of fees, though it remains unclear whether the city plans to levy any in this instance.
