Yeah, Steemit Inc. has been catastrophically mismanaged. Still, the deployed improvements have also taken too much time, including discussions, testing and such. RC took the best part of 2018; HF21 took 4 months to implement (and several months of sporadic discussion before that); and they still mucked both of those with at least 3 chain halts. The only efficient development in recent times has been SPS, unsurprisingly not done by Steemit Inc.
