The biggest stakeholders have too much power but sadly, that's the fundamental economics of HIve, so other than buying a few million Hive and staking it, there's very little to be done.
The issue is that the majority of these mega stakeholders care nothing about what they're voting on as it's all about maxxing curation for them. Even if the content is decent, there's often zero engagement from many users whose only reason for being here is to post and cash out.
