I get your point, but BuyMeACoffee is more than just a tipping platform. Creators can reward their supporters, showcase supporter comments (which is often more rewarding than the money itself) and much more.

MrDots is a game developer who gives away game codes to supporters. He raised $1300 within a day after sharing it with his audience: https://www.buymeacoffee.com/Zc2ryTOpw. This is just one of many use-cases where BMC can be used effectively :)
