I just wanted to give everyone a quick example of why you should always exercise caution when modifying an application’s privacy settings.
Facebook is rolling out a feature in the US that allows people to automatically identify and share things they’re listening to or watching. It’s important to keep in mind that this leveraging this feature requires that you grant Facebook access to your iPhone’s microphone. This means that Facebook will turn on your microphone every time you write a status update. It is worth considering the sacrifice in privacy compared to the convenience that you gain by leveraging this feature. Is it really worth allowing an organization to hear your conversations just so you can gain the ability to easily share what TV show you’re watching?
Facebook has stated that they do not record or archive these transmissions. However, using this feature requires that you trust that a 3rd-party (Facebook) will handle your data appropriately. Do you really need to provide them with this data? Does it really save you that much time to have your background noise automatically analyzed? These are questions you should ask yourself prior to providing Facebook with this level of access.
