I actually don't really care for friction shifting when compared to indexed... I like my drive-train to be nice and quiet. Generally when I ride, it's at a fairly leisurely pace and usually by myself on bike paths away from roads, neighborhoods, etc. In that situation, I find the need to adjust friction shifters to get rid of clicking to be kind of annoying if you don't have a nice shifting system like Cyclone or similar.

Anyway, I'm not saying there was excessive clicking throughout the whole video or anything at all. It's more just that there were a couple points when there was more clicking than there would have been with indexed, so it made it easy to pick out the shifting mechanism as friction. The bike I bought near the end of the summer was a friction shifter and I put a couple hundred happy miles on it before it got cold. It's not that I hate friction or can't use it. I just prefer indexed for ease and relaxation on a quiet nature-y ride.

Bet you didn't expect a two paragraph explanation to that one little sentence.
