I believe these protections are related to voice specifically, from what I recall. The law on record has to do specifically with voice data and excludes textual forms of data. If you were voice chatting over Facebook they would probably have to make you aware if they were listening/processing the data for words. By make you aware, it probably means bury it in the ToS on page 784 in a generic and ambiguous way and that is sufficient for court should someone litigate. Now when you start looking at voice assistants like Alexa, GA, etc. the waters could get muddier.
