Facebook is changing; in this particualr case it's a reorganization of the messaging functions into their own app. From Techcrunch, the predictable cries of frustration from people who are used to what they have.
Still, a unilateral forced migration is the exact kind of change Facebook users hate, and this will only breed more paranoia that their social network could change without their consent. Taking a slower “We’re switching everyone eventually, so you might as well do it now” approach might have gone over better than “Your familiar chat interface will be destroyed in two weeks whether you like it or not”.
We don't like it when our telescreen is changed.
The telescreen is from George Orwell's 1984. An excerpt -
Behind Winston's back the voice from the telescreen was still babbling away about pig iron and the overfulfillment of the Ninth Three-Year Plan. The telescreen received and transmitted simultaneously. Any sound that Winston made, above the level of a very low whisper, would be picked up by it; moreover, so long as he remained within the field of vision which the metal plate commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment. How often, or on what system, the Thought Police plugged in on any individual wire was guesswork. It was even conceivable that they watched everybody all the time. but at any rate they could plug in your wire whenever they wanted to. You have to live - did live, from habit that became instinct - in the assumption that every sound you made was overheard, and, except in darkness, every movement scrutinized.
