Light rewriting = moving some phrases around and changing some words with equivalent words just enough to pass an exact phrase Google test. Nothing major or too time consuming.
I think that's not really the right approach. Facts aren't copyrightable, but particular presentations are. Simply moving stuff around and changing some words created a derivative work, rather than an original work based on information gleaned from their work.
It's a gray area, and we surely want to stay very much on the "clean" side of that fuzzy line.
