I've had my phone number for... oh, 18-19 years. I assume it's utterly trivial for anyone who cares to find it, if they care to. I know it is, because I've had the occasional random call from people who wanted to give me a call for one reason or another.

And, certainly, Facebook suffers no consequences. A while back, some people noticed that if a company was in the news for a catastrophic data breech, their stock tended to climb immediately afterwards. No such thing as bad press coverage, at least in the age of the trading algorithms!
