Just below that metric, it links to MIT App Inventor[1]. It seems very disingenuous to post the statistics of a similar product with a tiny clause stating that those numbers aren't yours.
Honestly it would not have been disingenuous to exclude that tiny link clause altogether, but now they're being punished for transparency, because people are too lazy to click on the the "About" link for the page they provided.
