I highly recommend you read through the latest comprehensive discussion about increasing decentralization. I think you have been busy with other things recently and may not have noticed, but real progress is happening. Topics like periodic confirmation of neuron followees and grants for voting neurons have finally made it to the top of the priority list on the roadmap for DFINITY. The concrete proposals that have been offered are really quite good.
Below is the conclusion from the previous thread, but it really is a good read from the beginning because lots of people in the community offered well reasoned and civilized feedback.
