However, to me and also to many, many people who already left Hive/Steem for this reason - constant downvoting
As far as I have seen, almost no one has left Hive due to this. The biggest complainers who are "continually leaving" are, still here posting daily.
Censorship is actually suppression of content (usually for ideological or fear based reasons).
This is nonsense in regards to Hive, as no one is supressed. The only thing the downvotes do is remove the rewards associated with the content saying it. If that stops people from posting, that is their issue. They can also create a hundred different accounts and say exactly the same thin, over and over and over - it just won't get rewarded. People can still say exactly what they want and if people want to read/listen, they are free to do so. The argument is invalid. There are no repercussions for speaking her from Hive users, other than the opportunity to remove the rewards. The only reason people complain about it is that it affects what they can earn here, period.
