Los Angeles Times: Tinder has sent a cease and desist letter to the AIDS Healthcare Foundation after a billboard went up in Los Angeles last week that draws a link between dating apps and a growing rate of sexually transmitted diseases. The foundation said the billboard’s purpose is to raise awareness about the increasing STD rate and to encourage dating-app users to get regular screenings or a “free STD check.” The billboard features silhouettes of people and the words “Tinder, Chlamydia, Grindr, Gonorrhea.”
