@matigo More predictable for creators that weren’t using the per-post modes. Those who were patronised per post saw their patrons screwed with per-transaction fees if they were posting more than once a month. And if so, it’s likely their patrons were paying less per post, making the ratio of transaction fee to patronage amount substantially higher than with less frequent but larger sums.
It read to me as “yeah, don’t do that, do monthly, and we really want fewer small-fry patrons overall”.
