Excellent! CrossFit has had it with FaceBook's transgressions, and is pulling all participation from FB and it's Instagram service. See their announcement with details at
CrossFit, Inc. Suspends Use of Facebook and Associated Properties
CrossFit decided on this course of action after FB banned, without explanation or due process, a diet plan user group associated with CrossFit. However, their statement (linked above) gives eight major reasons for leaving FB. Note #7:
"7. Facebook has poor security protocols and has been subject to the largest security breaches of user data in history."
Other reasons among the eight include privacy violation practices and imposition of "utopian socialist" propaganda.
