Hive adoption is going to be orders of magnitude lower than Twitter. It takes significantly more effort to understand the mechanics here than Twitter - although my initial assessment is that the average person on Hive can reach a larger percentage of Hive users, compared to a similar ratio on Twitter.
I originally signed up for a Splinterlands account some years ago to play, noticed something about a laundry list of keys, copied them to notepad and played a few games of Splinterlands, and then didn't touch Hive for several years.
I've used Twitter for political causes to large success in the past, I've also used it to promote crowdfunding projects. Much of the userbase of Twitter either wants reactionary content - or wants something to be angry about. Twitter is effectively a dopamine trap.
My primary passion/hobby is performing classic literature on Youtube along with promoting a community of artists. Twitter isn't fantastic for promoting non-reactionary content. Beauty, or more thoughtful content get's lost in the noise.
In my experience, the censors really step into action when you are 'over the target' - meaning that they will allow topics and threads that generate controversy, provided that the main thrust doesn't actually expose topics that could cause their own controllers and 'team' to lose power/wealth or get into trouble. They present as if they are protecting 'the world' but predictably they are protecting themselves and their cronies.
