The freedom open-source software gives you may be priceless, but that doesn't mean you can't support developers nor should you take their work for granted.
Support your favorite open-source projects and their developers! Give them a chance to become self-sustainable! Lots of small contributions can make all the difference!
Do it, become part of the greater common good. It's not everyday you get to participate in a revolution! 😄
(No, I won't get tired of repeating this message. It's important)
@fribbledom The term "open source" was coined in order to refer to freely licensed software while explicitly avoiding the ethical and social issues of user freedom. If you're talking about freedom then you're explicitly outside the realm of "open source" and you're in the realm of "free software".
Depends on the situation and who the others are.
