I loved the idea, but I object to the symbology.
First off, we're against being seen. Why would we want a big creepy eye as the definition of success? Did Pirate flags show shackles and gallows? Of course not.
What are common pictograms associated with privacy? Shields. Locks. Locks on shields. Privacy is about defense and control.
Second, the blue gives me BSOD vibes. I get the EU reference, but black is super obvious here. Black it out. Redacted. Blind. All right there.
My suggestions? A shield or lock with dove at its center. Because the mass surveillance state is one of fear, not freedom or peace. Black field with blue and white stripes, white representing freedom, blue as you have it, and I guess giving a nod to Estonia's leadership in EU tech. Not that we need to rep Estonia, but I also liked their Eurovision entry this year.
