I absolutely understand your fears. Whether a project wants to finance itself through donations and whether these are only used for central infrastructure depends centrally on the type of project and community. Of course, it changes the motivation of the people if the amounts distributed become larger. We take this into account right from the start of the project:
LibreSelery should be seen as an alternative to Tidelift or GitHub sponsors. LibreSelery gives a FLOSS community the opportunity to distribute possible funds without further middlemen. We are convinced that funding within open source is ideally distributed via open-source software itself. However, as the commercialization and financing of open source projects is increasing, we wanted to present a concept that is more adaptable to different community requirements. In this way, it can be decided in a public process on the basis of a free tool how this is done.
