Free Will baby...

If the guy looked really nuts and sketchy then I'd probably say something and offer to drop him a line. But if he was solid on that initial polished section of FH in boots then I'd just clear the landing area and watch the show.

That's really the only thing that does bother me about free soloing on crowded routes is the potential of their fall to kill other climbers/people below. On FH you often will have a gaggle of idiots with dogs and babies milling around right at the base oblivious to gravity.

Now if he brought his cane with him up the route... That would be badass!
