> The first sentence explains that it is about how they are back on the defensive > Facebook endured a new wave of criticism from lawmakers and regulators in the United States and Europe on Monday after disclosures that the social media giant had allowed dozens of hardware manufacturers access to its trove of personal user data. I don't see any evidence of "defensive" action from fb. English is not my first language so maybe I'm misinterpreting being "on the defensive". If someone criticizes you are you automatically "on the defensive"?
