The intersection of 'evil enough to do something truly malicious', 'read a tech blog in the right 24-hour period', 'didn't already know the problem existed', and 'in enough cafes to pair with enough potential victims' is too low to cause "millions" more to be impacted by this, I promise.

Your implicit definition of 'highly motivated' (someone willing to put in 5 minutes of Googling) makes me sad.

I'm agitated because you're trying to hang someone for doing A Good Thing: putting real pressure on the bigs to finally actually fix a well-known, longstanding problem.

[Response to your edit: Facebook, Twitter, and other big sites know about the problem. How would explaining to them how Google secured Gmail change anything? They know how Google secured Gmail, and they know how to secure their own services. They just simply aren't, because it saves them money and their customers aren't demanding it. But the only reason their customers aren't demanding it is because the vast majority of their customers don't know the threat exists. This tool makes the threat clear as day to the most unsophisticated layperson, which makes it real, effective pressure, far more than yet another blog post asking nicely for SSL by default].
