If you go through the graphs and results, what emerges is that only the sweetener saccharin has that altering effect on the gut bacteria. I cannot find among the results any claim that the other NAS that were studied (sucralose and aspartame) have the effect.
The thing is that saccharin is not widely used any more. If saccharin is found to be harmful, that is nice to know, but not highly relevant.
