Your Facebook in this example would be open source information, the IC uses your info and produces an example of Open Source Intelligence by analyzing, applying context and a requirement. Your Facebook data in the intel product could be classified for a classified material purpose since it is a product of the process, but your Facebook data would remain open source information. That is where the Q 'intel' originates. The same data exists elsewhere and isn't sourced from an intelligence product.
OK.
It isn’t a “direct line” classification.
Makes sense.
