It already says it all? Just the name Rippel like you've said, is explicitly showing that it imitates the real ripple which is quite not sounds great. At this moment we should be aware on where to invest and avoid this one.
I see that this article wakeup biggest Ripple defenders and they are screaming now on the all corners of the internet how great this project is and how misleading and lying article this is. But I have to say that all question marks and red flags found by the author looks real and there is no proper answer to this accusation until now.
Let's wait and see how this case will evolve.
