It's known that NSA and even some companies in European Union have been working on global deanonymisation of BTC for a few years already - they have working prototypes for targetted deanonymisation, just need to let it work more globally. Snowden will just help spread this knowledge, which is always good.

And the "images in blockchain" thing is very old, so maybe that's why it isn't gaining traction anymore. There isn't too many people looking for pics in blockchain anyway.
