Introducing a minimum cut for Humble "creates even more opportunities to support important causes" because they need to "stay on mission" and because a bigger Humble means they can have more sales?
I generally lower the Humble cut to about 10% when I buy a bundle, and the logic of "we'll give more to charity by forcing you to give less to charity" doesn't wash.
Surely there's no real underlying reason for this decision other than "we're a business here", and to say otherwise feels false.
