I don't see it as stupid. I see it as an intentional delay tactic to maneuver around a regulator which, so far, acts far too slowly and imposes weak fines in response to flagrant privacy lawbreaking.

As long as Facebook can treat the fines as a cost of doing business they're happy. That, and as long as their (bullshit) value proposition of personalising ads by collecting as much personal data as possible is unaffected.
