I agree in so far as that RethinkDB didn't fail as an open source project. RethinkDB is a great piece of technology with an even greater community. But RethinkDB evidently failed as a company. The announcement indicates we might learn more about how it failed specifically but at this point it seems like it simply didn't achieve one of two things: become cashflow positive or gain another investment/acquisition. It also seems the open source project will live on.
