Because it's open source, payments are optional. Yes, including by big companies. Even those who want to "give back" have lots of options, such as "paying it forward" by making something else. There are people who give away software, support it (at least making security patches), and are fine with other people relying on it. If that's you then publishing it as a package makes sense. But a lot of us are not really prepared to do that with the software we write, and we should be wary of the implicit promises we make with how we publish it. Publishing example code or a notebook is safer since no library is going to add a dependency on that code.
