It won't 'protect' you. They still track you and have a shadow account for you, and sell the data. FB is a cancer that won't go away until we/you do.
You can protect yourself by blocking all 'social media buttons' (as LI or Pinterest do the same), and for FB block every domain they use and their range of IPs. But there are so many trackers that will (eventually) get the 'job' done, so you either do 'more' (replace hosts file, add firewall on your Android and block ad broker, doubleclick, adjust, mopub, google analytics, etc. etc (loooooong list).
Surveillance capitalism is not going anywhere. Where money can be made, money will be made.
