These things are true. However, how stake is wielded is determined by what incentives are given stakeholders. The incentive to accumulate stake to impact governance is both positive and negative, depending on how much you can accumulate. If you can accumulate enough to become a potent factor in a majority stake coalition, you have strong incentive to acquire it because that coalition can manage code to benefit them. If you can't accumulate that much stake, you have a disincentive to maximize your stake because governance will be managed by a coalition of stakeholders that are managing the platform to benefit themselves.
