I agree with this. In an official DFINITY Medium article from 2021 titled “Getting Started on the Internet Computer’s Network Nervous System App (Wallet),” the team clearly stated:
Users benefit the most if their neuron attains its maximum possible value. When considering the locked neuron, that moment is always “dissolve delay days” in the future, which comes closer every day that a neuron is dissolving. Meanwhile, the long-term success of the network will best be served if neuron owners vote with a long-term view toward maximizing the value of the network in the distant future. For such reasons, the NNS incentivizes neuron owners to make their dissolve periods as high as possible by disbursing greater rewards to neurons the greater their dissolve periods, which can be configured up to eight years.
As a result of this incentive structure, a substantial portion of ICP holders (61.5% of staked tokens) locked their tokens for the full 8-year period. These holders now receive approximately 15.6-16.1% in annualized rewards
And now while most of us are locked for 8 years, we would only receive approximately 2x the rewards (15-16%) compared to the proposed 7.66% for 3-month neurons, despite being locked for 32 times longer. This reward-to-lock ratio is extremely unfair to long-term stakers who committed to supporting the network’s stability.
If you want to implement shorter lock periods, I suggest a truly proportional approach based on duration. For example, 3-month staking should start with a much lower rate like 1.1%, with a progressive system where rewards scale more fairly with commitment length, leading up to the maximum return percentage at 8 years. This would properly incentivize longer-term commitment while still offering flexibility to those who need shorter lock periods
