Technically, no. Legally, it means you haven't accepted their terms of service, so if/when (I hope) the political privacy landscape changes, it'll be more likely that you can sue, report a violation, request deletion, (or maybe they'd even preemptively delete it to cover their tracks / come into compliance with new laws).

That's an interesting thought. I've removed (deleted?) my Facebook account several months ago. Maybe I should have kept it around in order to manage it.
