I interned at Facebook a few years ago, so I&#x27;ll speculate with an ounce of information.<p>There&#x27;s a lot of openness, including around issues like this, at the company. There&#x27;s weekly all hands meetings, where a developer could directly ask Mark about his opinion on a feature like this. The user experience, including creepiness, was almost certainly discussed. They may have misjudged in this case, but that&#x27;s fallibility, not because it was ignored.
