I think they changed the name because new users would constantly be confused and think Haveno and Haveno-Reto were the same thing, so they changed it to RetoSwap to distinguish themselves as a seperate from Haveno.

We will see their plan anyway, and there will have more instances in the future for sure, maybe intentions are good as you suggested and I'm too paranoid ? But don't fuck with us Reto it will not go easy this way
So far, nothing has led me to believe Reto is a bad actor. More the opposite. But yes, I'm sure there will be more instances that pop up over time. There is a new one called Aloha, but I havent read very good things about it...
