There are a variety of these people, ranging from people like Press For Truth and Derrick Broze - who do post on Hive, despite having been heavily downvoted in the past - through to people of all political persuasions who say they value freedom. Some are true freedom lovers and some are perhaps in it for the money. Some are deliberately placed agents whose job it is to direct people back into 'the matrix'.
In general, my conversations with such people have been limited in terms of their use because there are no decent educational materials for Hive - not even a single well made video to promote it. So they identify flaws in the system and often don't have anyone to direct them on how to overcome them. They have often also tried to use Hive and found it either too challenging or they have been heavily downvoted. They can generally put their energy to better use on even the more controlled networks, because the audiences are much larger and they have an idea of how to navigate the pitfalls.
Creating influencers in the truth movement is not a simple thing to do - it's far more effective to work with the people that the internet already trusts. Ultimately, if Hive can't onboard even the people who most naturally would value it - then that's a Hive problem and not much else.
