I think of the whole downvote drama as rewards disagreement. Just as anyone is free to upvote content they support, so should anyone with stake downvote content they don't support as a consequence of freedom. Regarding censorship, people can still access what is posted on the backend even if the frontends don't display them and they can still get searched on google crawlers. I searched for those users that have negative reps way down the negative and their content can still be visible.
No one can deplatform you on Hive, you just don't get the social rewards of the 1st layer for the downvotes. But the second layer is another option where some tribes have a frontend that enables you to share your content and have it visible.
