I‘m serious when I say that without people like @stux and his team, who invest their free time and money, we wouldn’t be able to benefit from all the great advantages of open-source community projects. They are the reason why we have such good alternativess to Twitter or WhatsApp (regarding Signal).
People, who are using this freely available software should really be happy and ask how they can support these projects. Remember, while donations might be the best immediate help, it is also very crucial for such projects to raise awareness and spread the word. That way, more and more people can enjoy the work of FOSS developers and the developers themselves can enjoy seeing how their work creates a huge community that everyone wants to be part of and contribute to it.
And I tell you this from the perspective of a developer of an open source project who knows what that means.
