I think you are misconstruing the U-video. The testing on chains that you alluded to that determined they were “compromised”, was done on twisted chains -as in a single length of chain twisted causing the position of each individual link to be distorted from their normal end to end position in relation to each other.
The video per your summation, showed two chains being wrapped around each other. There was no indication in your summation that the position of the individual links were distorted from their normal end to end position. If this is so, I don’t think that this “wrapping” has ever been tested and proven that it makes the chain weaker. In my mind, it could go either way; and hence Smokey the Bear may not be spreading misinformation.
