Publish0x recently lowered the minimize tip split percentage from 20 percent to 10 percent.
This means you can tip the author as low as 10 % of the total tip and keep up to 90 % to yourself for reading the post.

Do you see this as a good thing,?
Personally, I don't mind. While I vary my tip percentage split, there are times where I just feel I should keep the bulk for myself.
Truth be told, thesedays I struggle to find content that I see worthy of tipping more than the minimum. So many of them are just regurgitation of content from other platforms. And some posts are not even edited. As an example I might see "As a gift to all Medium members..." and so on.
