This is a solid way to support open source maintainers. Another way I have seen companies support open source is by hiring these maintainers as employees or paying an employee to work on the open source project. Of course, right now this is happening at popular open source projects like Kubernetes and is only followed by big tech companies. But, giving some time for internal developers to contribute back to the open source project directly can have a huge positive impact as well. This is not an alternate solution to actually sponsoring money but something that could complement it.
