Ask HN: Why don't form-fitting Faraday iPhone cases exist?

I've been researching privacy tech and noticed something odd: Camera slider cases exist (Spy-Fy, etc.) - they block physical camera access but offer no signal protection. Faraday bags exist (SLNT, Mission Darkness, etc.) - they block all RF signals but you have to remove your phone from its case and put it in a pouch. But nobody makes a form-fitting iPhone case that integrates both - a ...
