GMA,
Sadly, yes, the Chinese Daredevil was paid $15,000 by some local company for that stunt, although he had previously earned a reputation for climbing/dangling from skyscrapers, which is why he was approached with the $15,000 offer. I agree with the remainder of your post that the Spiderman in France made that climb look MUCH easier than it actually was or would have been for the average person. I tend to doubt anyone posting here could have pulled it off as easily and quickly as he did.
One other thing about the specter of hanging/dangling in mid air for a period of time: many years ago I was involved in a case in which a guy went into the attic crawlspace of a building with very high ceilings over an atrium (for the work related purpose of inspecting equipment stored in the crawlspace). While in the crawlspace, he slipped off one of the wooden joists above the sheet rock ceiling, and plunged through the ceiling. On his way down, he somehow managed to grab, and hang onto, a horizontal wooden supporting beam just beneath the ceiling. He dangled for around 5 minutes, screaming for help, before he couldn't hang on any more. He fell around 35-40 feet onto a marble floor, and suffered many broken bones as well as a perforated bowel that necessitated around 12 surgeries. Around a year later he got out of the hospital and I remember the guy saying those 5 minutes when he was hanging were sheer terror- he knew if he was not rescued it was going to be a fall that would result in his death or severe injuries, and he got the latter. He was never able to work again in that field.
