I've been meaning to start giving more money to free software projects I've benefitted from. Sadly, a lot of them don't take donations or they use some convoluted payment processor. I would totally be willing to support a project through something like Patreon and pay something like $3 per minor release and $7 for a major release. This should be a no brainer for smaller companies that can only afford free software but also want that software to be well supported.

Even as an individual, I don't know why I haven't set up donations on my github projects. Some of them have several stars, and you never know who will buy you a beer or a coffee.
