@TheSugarRay, I think it is a way to universally promote content creators so they do not have to resort to advertisemnts to make a little scratch on their content. The brave browser has a similar monetization concept built in, and I have been using it and contributing to creators passively while not engaging in ads, and love it.
So i would think of it being less of a tip jar, and more of a replacement for monetizing with advertisements. Ko-fi is exactly a tip jar IMO, and these are two very different and useful things to have.
