The browser extension, Missing e… modifies the look and feel of Tumblr to add several new features — something that Tumblr has taken issue with for months…. This puts Tumblr, known for its stance on SOPA as a champion of user rights, in a bit of an awkward position: In this case, it’s the entity seeking to block access to a popular and by all accounts useful piece of software.
The result, it seems, is a return to the age-old tension between users’ desire to get more out of a platform than it was designed to offer and a platform’s need to control its product. We’ve seen it with Twitter, Dave Winer notes, we’ve seen it with Facebook, and now we’re seeing it with Tumblr.
