Since Mueller isn't a lawyer, and his only other credentials are being a paid lobbyist, yeah it matters. Sure a lobbyist might be correct, but why would you trust them for information to begin with?

And looking at his post with a sceptical mind would have you learn his only third party source is a magazine whose tag-line is "Maximising IP value for business".

Even if correct his post is blatant propaganda. In fact, I'd go so far as to question why he chose today to register an account on hacker news. This isn't the first patent related news we've seen.
