I mean, they explain it at the top:

> we track our own GitHub star count along with that of other projects. So when we spotted some new open-source projects suddenly racking up hundreds of stars a week, we were impressed. In some cases, it looked a bit too good to be true, and the patterns seemed off

If their competitor has fake-looking star counts, I'd expect them to be the ones best equipped and most likely to suspect it.
