It depends on the type of fruit though, since there are some fruits that won't set properly with the low-sugar pectin. (This only applies to home canning though, since the industrial manufacturers should have access to other thickeners.)
It really depends on the fruit though—most of the time it works great, but there have been a few fruits that wouldn't set at all (closer to a syrup than a jam) with a low-sugar recipe, but set perfectly when I added more sugar.

Agreed 100%.
