Try to get the projects to accept Bitcoin.

Bitcoin!

Don't. You better donate to libre projects and ask open source to go libre. Open source just misses the point.

Go to their Web sites and ask them if they are a libre project or an open source project. If they are the former, ask them to call themselves libre, not open source, because open source just misses the point. If they say they are open source, ask them to call themselves libre, not open source, because open source just misses the point. If they accept, donate.

Go to the project's website and find the donate link.

Most of these projects have donations links on their websites.
