I'm guessing he was just open and honest to all of the founders and sometimes being open when you run a huge VC firm is a risky challenge. So not recording it means he can offer insights without a clip of it going on TechCrunch.
Maybe not controversial but just talking about portfolio companies or commenting on them directly can be risky when you have a big fund and LP's to deal with.
Agreed but there's a difference between being on video and someone writing about your talk. Some people just don't like the pressure of a talk being recorded and prefer people to write about the general talk if they want to write about it.
