It seems obvious why they interview him...they LIKE him. In the human sense, not as part of some nefarious plot to undermine Bitcoin.

You'll see it in the way the interviewer introduces him, addresses him, and closes out the interview.  Anyone who talks to media-trained suits day after day will be refreshed to talk to someone as sincere and accomplished as Amir, who is happy to rock up to the studio in a hoodie and talk street English.  I've met Amir a few times and he is eminently likeable, and it seems this debate is partly a division between those who know him and those who don't.  It's also a split between those who think rhetoric is needed to convince the world to use Bitcoin, and those who think a fully-functioning blockchain and ecosystem is what will convince the world to use Bitcoin.
