The language sounds too slippery to me. Implementors won&#x27;t be sued, they say, but who decides who is an implementor? What is an implementation and what is an undesirable hack? Who is a security researcher and who is persona non grata?<p>If I make a time shifting system, to use the article&#x27;s example, but the standard says the protocol must be played live, am I an implementor of the standard, or a nefarious hacker?<p>What if I create software which lets people abroad watch content from PBS Nova (currently blocked by geo-IP)?<p>I might even screw up and implement something usable for &quot;bad things&quot; by accident. Am I then an infringer, if I neither properly implemented the standard nor conducted research on it?
