The site noted the declining number of websites that support pornography and nudity, writing that 'much of that attitude has grown out of Apple's strict controls over the App Store and the iOS ecosystem'. 'With its massive distribution and strict rules, Apple's App Store has had a broad homogenizing and sanitizing  effect on the internet,' Motherboard wrote on Monday (local time). The decision comes just weeks after Apple dropped the company's software from the App Store after child pornography was found on the site, raising questions about whether Tumblr's decision was related. For years, Tumblr has been known for the sex-focused subcultures active on the image-forward service: Those sharing and making explicit fan fiction and art, amateurs and hobbyists, and LGBT erotica and pornography. The company did not say what prompted the change. * Google joins Reddit crackdown on nude posts
