(FOXNEWS) — CrossFit, the branded workout regimen, accused Facebook of being “utopian socialists” and left the platform after the social network deleted a group dedicated to a diet.

The move to quit both Facebook and Instagram came in the wake of the decision to delete “without warning or explanation the Banting7DayMealPlan,” a group that advocated a diet aimed at eating “food that is as close to its natural state as possible — free from processing, additives, preservatives and sugar.”
