The conclusion of that article is that the model doesn't work because of processing fees and friction from entering information.

The author discounts Bitcoin because it has high fees, but some cryptos have 0 fees and others have very low fees. With crypto you also don't need to enter any information, simply scan the QR code and enter the amount you'd like to pay.

If crypto was adopted, the model would work just fine.

Personally, I always donate 10 cents to a dollar in Monero when I read an article[1] that I enjoyed that offers crypto donation addresses. Primal[2] has built a crypto wallet into their app and you can see people send "zaps" of Bitcoin when they appreciate a post and it has adoption.

Acquiring and managing crypto is its own form of friction though.
