For me, it puts a comfortable professional distance between public projects and real accounts, and it reduces friction on pseudonymous and international payments. Banks and credit unions in the US usually have a bill pay system to send checks or e-checks for free. Some people do use it to contribute to projects, sometimes even as a recurring donation, but it's rare. I'm not sure it would be so cheap if it weren't rare.
