That IMO means that the posts in the "Public" Stream are shown in the same order as they were timestamped on the blockchain.
I know that this statement is only true in theory as upvoting/upvalueing changes the order of the "Public" Stream.
So, if no-one would upvote any post, the order of the posts here in the UI would resemble the order of the Treechat transactions on chain (see whatsonchain).
It's not like other social media platforms that have a (For You) biased algorithm that decides what you see and not see. Their platforms are moderated and shadow-ban or remove posts that doesn't their policy. (Remember the coughit period).
