Sounds like a mass mailing scare tactic to me. Just ignore it. Maybe the nigerian scam emails are not as profitable anymore and they are finding new business models.
Remember, that bitcoin is not a company. There is no headquarters. It has no CEO. Bitcoin owns nothing, nobody works for bitcoin. Bitcoin is a protocol, it is a mathematical framework for securing value transfer on the internet and it is implemented in computer code that you can run on your own PC. If you install this software, and run it, then you are part of the bitcoin network - but you would not consider yourself to be bitcoin. The same is true for everyone who runs this software on their PC - they are part of the network but they are not bitcoin.
Roger Ver, who owns bitcoin.com, has himself been the target of extortion attempts. Twice.

Other prominent people in the bitcoin-space have also been extorted (or attempted). This includes Hal Finney, who is one of the very first people to work on the bitcoin protocol.
Doesn't sound like you will have to go to the extent that Roger has gone to. He pulled a "Ransom"-movie style inverse bounty on the hacker, rather than pay up. I respect that.
