If you are referring to Java, I would point out: Oracle's JDK is based on Open JDK. Open JDK is licensed under GPL + the classpath exception. (eg, the Open JDK is under GPL, but when used as a runtime for other software, then that other software does not come under the scope of the GPL.) There are multiple other sources to get pre-build binaries for the Open JDK without going to Oracle. Azul Zule built for multiple platforms including Linux, Mac OS, Windows. https://www.azul.com/downloads/zulu/ https://www.azul.com/downloads/zulu/ And Zulu for Raspberry PI: https://www.azul.com/downloads/zulu-embedded/ https://www.azul.com/downloads/zulu-embedded/ Open JDK Build: https://github.com/ojdkbuild/ojdkbuild https://github.com/ojdkbuild/ojdkbuild (click the 'releases' link) Adopt Open JDK: https://adoptopenjdk.net/index.html https://adoptopenjdk.net/index.html (offers choice of HotSpot or IBM's Open J9 technology) There's also Red Hat, for free, but you must create an account. And IBM makes their own builds, but they are typically bundled with some other product such as Eclipse, so a bigger download.
