This is unbelievably concerning because Facebook is pre-installed on many phones now, and Facebook's apps send your out-of-app SMS messages to Facebook. This is part of the reason I quit the app; Literally gathering up my texts and keeping them on their servers without my knowledge or direct consent is an overwhelmingly huge violation of privacy. This is why I recommend everyone download a copy of their Facebook data. If you still have an account, you shouldn't.
the data is already up there, everywhere... instead of deleting facebook account just be a regular joe; never post personal stuff, just memes or scientific things, news
this way wherever they data mine your data it will only return crap
This is not enough in my opinion: even if you are not sharing anything important, the fact that you are playing a role in a social network means you are pushing your friends into sharing more data.
