Yeah, that's a bad look for both dgraph and the new company imo. What guarantees the same thing ran by the same people won't have the same issues again?
Not only that, if the core team moves to the open source product to "rebuild" the same features, isn't that way too dangerous IP-wise?
This is also one of the reasons I didn't use dgraph: Open source core doesn't work. All the companies that were sold to now have nowhere to go for support.
