Bitly, a URL “shortening” service and link management platform, has reportedly blocked all links associated with distributed systems expert, Andreas Antonopoulos’ book titled “Mastering Ethereum.” Antonopoulos, a well-known and highly respected Bitcoin (BTC) maximalist, publicly addressed the issue with Bitly, a New York-based privately held firm. There were about 200 links related to Antonopoulos’ new book that had been blocked, according to various social media users.
